I'm trying to do an fminsearch on a function with three free variables and I get the following message : ??? Attempted to access p(3); index out of bounds because numel(p)=2. Error in ==> @(p)lorfit(Table1,p(1),p(2),p(3)) Error in ==> fminsearch at 205 fv(:,1) = funfcn(x,varargin{:}); here's the code for my function lorfit : function [ ansa ] = lorfit(x,G,x0,H) ansa = 0; for c = 1:length(x) ansa = ansa + (x(c,2) - (H/(2*((x(c,1)-x0)^2+(G/2)^2))))^2; end ansa = sqrt(ansa); end Can someone tell me what I'm doing wrong?

Whatever code is calling FMINSEARCH is apparently calling it with a starting vector that has fewer than three elements. Set a breakpoint at that line of code, run it, and see what's being passed in. Hope this helps.

Hallo, Der Versuch mein Programm "ITS_90_converter2(2,'S',1e-2,3e-5,4e-6)" in Mathscript laufen zu lassen scheitert. Ich denke fminsearch findet die zu minimierende Funktion (myfun2) nicht, oder liegt der Fehler wo anders. Coefficients und Coefficients_invers2 liefern keine Probleme. Oftmals h�ngt sich die Software auch auf und muss neu gestartet werden! Eingabe Parameter wie oben, Matlab antwortet:ans = 273.9756F�r ein Tipp w�re ich sehr Dankbar! Ausserdem: lassen sich global's eleganter schreiben, als ich das getan habe?Gr�sse ni2.7z: http...

For a while, I wanted to try Vista on my home PC but few things were holding me back. I had heard there were no Vista drivers for my Canon scanner. The OS was a bit too expensive and finally the whole EAX-Alchemy support (or the lack of) for Audigy2 had left me a bit unintrested. Then two things happened that made me try the new OS. The local Frys Electronics started selling a 300GB SATA2 hard-disk for $69 - a perfect way to try out Vista by setting up a dual boot. Secondly, I found out that pretty much any version of Vista can be installed without having a valid key and be tried for four mont...

Hi guys, i give up finding a solution by reading or by trial & error. Hope, YOU can help me! (Sorry for my rather long posting.) Stroustrup says, that templates could be declared with - type parameter, e.g. template<class T> - parameters with *simple* types like int, e.g. template<int size> - template parameter, e.g. template< template<class> class A > the latter beeing a type specifier, not an instance of A. So, there is no way to declare a template class with an *object* of my own (template) class A ?? I want to declare a template class giving it ...

Hi, I have to minimize a function w.r.t. certain parameters, but the parameters themselves are bounded and assume values from a set of intervals. Is it possible to incorporate it in ordinary minimizer, something like fminsearch or gradient based methods? I may try to make value of function infinite when the parameters are outside the range, but I don't know how the minimizer would perform given then the function would no longer be continuous/differentiable. Thanks Chris ...

Hi, a very simple question. I am trying to understand inheritance using c++ and dont cee how i could use three classes to create an accounting program using inheritance. e.g one class containing members for both, and then a class for checking accounts and a class for savings. Finally could you just clarify that this is the correct use of i nheritance because i am thoroughly confused.

Hi! I have this math model, with witch I have to describe the experiment. I have to find model constants. So I optimize my model, until Standard deviation of experimental and model data is less then 10e-04. Model data is calculated from a system of 2 part diff equation. So I use pdepe, which is solved under fminsearch. I have a function that looks like this: k = fminsearch(@SD, k0); k ... parametar I have to optimize SD ... Standard deviation function @SD looks like: function y = SD(k) y is gained from Experimantal vaues and Math model values math model values are gained from system of 2 pa...

Hi, I'm pretty new to Python, to programming overall...so how would I make something where the user inputs multiple words in a string - like "connect 123.123.123.123 21 user password" or similar, and then I can split this string up to pass these arguments to a function like ftp_connect(ip, port, user, pw) etc...? I have no idea how to "break" the string up so I can get these out of it.. thanks for answers, munin mercuryprey@gmail.com wrote: > Hi, > I'm pretty new to Python, to programming overall...so how would I make > something where the user inputs m...

Is there a universal method (valid for all C compilers) that avoids the compiler to generate a warning about a not used parameter of a function? I think it isn't because compiler warnings aren't regulated by the standard. So I'm wondering what could be the best or the better methods to face this situation. I tried with the following on my compiler: int sum(int a, int b, int unused) { unused; return a + b; } but it works only with a low level of warnings. Otherwise I can do: int sum(int a, int b, int unused) { unused = unused; return a + b; } ...

Hi, I would like to know if how would fimisearch work with a set of simultaneous equations, for example: function w=something(...)

What if wanted to minimize only the first line and use the second one as a restriction? The problem is that I want to minize a function that has a variable that is defined in another function that has endogeneity problems. I would really appreciate if anyone cou...

Hi all, Now I need some help. First I want to know a term:VCxBULK. For example, VC12BULK in STM-1. I think it is a whole payload area of STM-1which is filled with VC12. And its rate is equal to 155M. Other payloads as VC11BULK,VC3BULK,VC4BULK are the same rate as VC12BULK,155M. The difference between them is mapping structure only. What kind of testing or situation will use these payloads? You konw, in the most often testing, we use STM1/VC4BULK to test STM-1 interface. What purpose will use 1.5M,VC11BULK,2M,VC12BULK...? Next is about propagation delay.Is there any recommendation or specific...
