Using "fsolve": How to control iteration using "residuals" and "norm of step"??

Hello Everyone,

I am using fsolve to solve a system of linear equations and it’s working fine. However, I have a coupe of issues:

(i)	Even when the solution (alpha) converges, I am getting the message to choose a new point. I am guessing that it has to do with “norm of step” as probably the code is trying a smaller step. 
 I am using option like this:
options = optimset('Jacobian','on', 'algorithm', 'Levenberg-Marquardt','Display','iter-detailed', 'MaxFunEvals', 10000, 'MaxIter', 10000,'TolX',1e-6);

(ii)	I do not need this much precision anyway and I guess that the function tolerance of .01 would be good enough for my purpose. However, when I try to set it like this:

Of course, the value of alpha has not converged. So, it seems that I am not using “tolfun” the way I intend to use it to control residuals. As you may remember, I am solving a series of nonlinear equations.

I would really appreciate if someone tells me how to control “residuals” and “norm of steps”.

Also, is it possible to display the value of alpha during EACH iteration using 'Display','iter-detailed'?

Any help would be appreciated.

Thanks,
DK

When to use "." and when to use "!"
I'm still confused about this and I can't find anywhere that explains it properly. I have the MS book "Access 2003" in front of me and I'm reading Part 5 about VB and so on. It's telling me about how to refer to a specific database and has the example:- Dim dbMyDb As DAO.Database Set dbMyDb = DBEngine.Workspaces(0).Databases(0) but, but, but, but - what do those dots (periods, full stops, call them what you will) mean? (OK, it appears to be the same usage as C/C++/Java when referring to class/structure members, but I wish it would tell me that somewhere) Why are there dots used in referring to object members in this case but when referring to controls on forms (for example) one uses "!". Surely there must be somewhere that helps one understand this basic syntax. -- Chris Green Generally, a dot exposes properties and methods and a bang (!) exposes members of a collection. So forms!frmMyForm.Visible refers to the visible property of frmMyForm, which is a member of the forms collection. What makes this harder (or easier, depending on your perspective) to grasp, is that Access has gotten more and more forgiving about using the "wrong" notation. usenet@isbd.co.uk wrote in news:44316bba.0@entanet: > I'm still confused about this and I can't find anywhere that explains > it properly. > > I have the MS book "Access 2003" in front of me and I'm reading Part 5 > about VB and so on....

Invalid use of "." "!"
In writing a sql statement I get the error "invalid use of "." "!"......... this is apparently coming because the where clause of the sql statemt refers to a combo box with sales persons names in it. All the names are listed first initial followed by a "." and last name. I am assuming the error i am getting is coming from the "." in the combo box. How do I get around the invalid use of the "." ?

What type "T" or "auto" should I use for i?
What type "T" or "auto" should I use for i? - C++ 11 allowed template<class number> bool is_zero(const number& n) { for (T i = 0 ; i < n.digits(); i++) { if (n[i] != 0) return false; } return true; } The objective is to have a correct and fast code. Mathematically speaking, the value returned by digits() and the value of i are both positives integers. The value returned in digits() can be converted/stored inside a computer using some integral type available in the C++ language. The type used to index operator [](type index) is also some C++ integral type. I have control about the "number concept", but I don't want to add "computer" details. For instance, I could add to the type the maximum number of digits allowed. struct number { static const some_integral_type max_digits = some_value; } but I don't want to add typedefs like size_t, bits and bytes.

what is the difference between "tsu", "su" and "sudo"?
Hi all I needed to ask a question about the Linux commands used for getting root access. The question is, what is the difference between "tsu", "su", and "sudo"? I am mainly interested about the "tsu" command regarding which there seems to be very little documentation. What is the benefit in using e.g. "tsu" rather than "su"?

Context syntax proposals, using "with", withing "use" etc.
After watching for some time the prolonged dances around "with and use", I'm inclined to contribute to the topic. First, I'd like to say that all the arguments concerned with repeating of a package's name aren't serious at all: as for extra typing, this is a matter of a text editor, not of the language; and as for a possibility of mistake (that is, placing an unintended package's name in "use"), it is a matter of a style and a corresponding style checker compiler option - you have little chance to get such a mistake unnoticed with a quite simple rule: for example, always place "use" and "with" in the same line, and never mix different packages in the same line (compiler can easily verify that). Second, there is still a displeasure here, which can even become a hindrance in some circumsrances: when there are many context clauses for a package, they just occupy too big part of the text; and because those context clauses are necessarily at the beginning of each package, they intersperse and clutter the whole program, which makes reading more difficult (even if each package has its own window) - if one tried not to study thoroughly, but just to read and catch the general method\logic\approach of the program. So my guess is that the real reasons demanding the changes for "with" and "use", if any, aren't about repeated package names, but actually about overall amount of the text in (all) context ...

I have the same problem. Please share if you can. P. I don't know if it helps but there are some entries on the File Exchange that appear to combine MATLAB and ANSYS: http://www.mathworks.com/matlabcentral/fileexchange/?term=ansys Failing that, you guys might want to describe more what kind of interface problem this is. What output does ANSYS produce (A data file? An ASCII file?) and what precisely are you trying to read into MATLAB? Dear sir, I am working the optimization of composite plate and other composite Structures. I have to run the ANSYS with MatLab Optimization code. I have Optimization code. My intension is to run the ANSYS by taking the MatLab output results without Graphical User Interface. The code is generated in such a way that it takes the changes of the thickness and othe...

"refreshdata" against "set"
Which one is better, "refreshdata" or "set"? Simply by looking at the code I've noticed that refreshdata does: 1) Finds all the properties of the object which end with 'DataSource' 2)Evaluates all of the relevant variables in the upper workspace 3) Does set(h,....) It looks like there is no advantage in using refreshdata, as it ultimately calls set, but does bunch of other operations. In my GUI, I've implemented polygon movement with both, and using directly "Set" is much smoother. Please correct me if I'm wrong. ...

"Ritual" is "MumboJumbo"
Well it looks as if Ritual has been "saved". Don't know if we'll ever get to see a SiN Episodes 2 or another Painkiller, but at least this bunch of talented people have jobs in the industry still. MumboJumbo are better known for casual games like Luxor. Let's hope they decide to branch out a bit and venture into the Action/FPS games market. Somehow I can't quite see myself getting over excited at the prospect of "Super Collapse: Episode 3- Revenge of the Orange and Blue Marbles". http://www.bluesnews.com/cgi-bin/board.pl?action=viewthread&threadid=74809 -- Rob Rob wrote: > Well it looks as if Ritual has been "saved".

svmon "virtual" vs. "work in use"
Hello, on nearly all of my systems, those both values are more or less the same, f.e.: size inuse free pin virtual memory 1572864 496929 1075935 82182 173205 pg space 1048576 696 work pers clnt lpage pin 82182 0 0 0 in use 173218 323711 0 0 Just 213 pages more at "work in use". I never noticed big differences on my nodes regarding these values, thats why I never cared about the difference. Now, however, I noticed that on one system virtual is double, sometimes 3x as much as "work in use". This is a mq-system where we have application-related problems, thats why I am interested in this "special behaviour". What are the differences between those values? What is part of virtual, but not "work in use" and vice versa? All I know is that the text-segment is part of "virtual", but not part of "work in use". Regards, Holger ...

use "old" .so-files with "new" compiler?
Hi, I am quite sure this question has answered here already several times, but I haven't found the answer yet. Anyway, here is the question again: I've got libraries (*.so) that are built with gcc 2.95.2. The gcc version, I've installed on my computer, is 3.xx and I don't have the source files of the libraries. Can I link those libraries without uninstalling my new 3.xx-compiler? Thanx for your answers in advance. Isn't there a secret flag like "gcc -useoldlib"? *g* Philipp "Philipp" <capri.sonne@gmx.de> wrote... > Hi, I am quite sure this question has answered here already several > times, but I haven't found the answer yet.

Dijkstra's "Enumeration" = "Metrics" his "Abstraction" = "Quality"
"Enumerative reasoning is only an adequate mental tool under the severe boundary condition that we only use it very moderately. We should appreciate abstraction as our main mental technique to reduce the demands made upon enumerative reasoning." ~ EW Dijkstra This is critically decisive because Dijkstra is saying that in most *software engineering" contexts, most of the time, abstraction is key relative to "metrics", the numerical, the quantitative. It is a TOWWWEEERRRING, grand slam "home run". It is of Doug William's 3-4 perfectly pitched Super Bowl touchdowns. It is growth in insight after Dijkstra one of THE very best ran into major impasses attempting to drive development with metrics. His insight is that ABSTRACTION should "lead" the way. While there is the dialectic: metrics<=>abstraction The predominant factor to engage and lead software engineering by is "abstraction". So notation wise better: metrics<=>abstraction* And to denote analyzing or summarizing the dialectic applied in whatever context, from point 'a' to 'b': a,b{ metrics<=>abstraction* Discrete points: a,b; l,q{ metrics<=>abstraction* Have at your own meaningful fun!
