Bugs in Matlab Robotics Toolbox R6 ????
I am currently using the version 6 of your toolbox. I understand there
is a bug for version 7. I wonder if the bug applies to version 6 as
well. From the version 7 website it is written:
"There is a bad bug with rne() for the case with friction and gear
ratio greater than 1 (eg. the default puma560) model. The friction
torque is too big by a factor of the gear ratio. This problem exists
in both the MEX and M file versions. This zip file contains 3
replacement files, unzip it in the Robot Toolbox root directory. If
you use the MEX file then you'll have to recompil...errors in using matlab
I met a problem with error message saying "Invalid MEX-file '/root/2008b/bin/spm5/spm_slice_vol.mexglx':
/root/2008b/bin/spm5/spm_slice_vol.mexglx: symbol mxGetNumberOfDimensions,
version libmx.INTERNAL not defined in file libmx.so with link time reference." I tried to search the reason, but found no solution. Does anyone have any idea? I'm totally lost.
The matlab version is 2008b.
Thank you in advance!
...matlab functions and structures
I am wondering if it is legal to return a structure from a matlab function. Also, is it allowed to take as input to a function a matlab structure. I would appreciate some examples if it is possible to do so.
In file test1.m:
inputStruct.v1 = 42;
inputStruct.v2 = 69
outputStruct = MakeStruct(inputStruct)
function outputStr = MakeStruct(inputStr)
outputStr.Value1 = 10 * inputStr.v1;
outputStr.Value2 = 10 * inputStr.v2;

I know that if you click on a face, and use the measure tool,
SolidWorks will give you the area of that face. If the part has a hole
or multiple holes in, this area isnt calcualted. What I need though is
the square area of the part. In the example image below, the hole in
the center would most likely be scrapped, unless someone nested a small
part in that area (which doesnt happen much here).
Is there a way to get this value automatically? Macro maybe?
"SW Monkey" <google311.50.spydermonkey@spamgourme...Linux is power squared
Linux is power squared
The thing about GNU/Linux and open source I like most is
the entire ecosystem is power squared.
Doing something requires tools, and if they are free
and readily available, then time taken to complete a
task is reduced by the square of the number of tools.
Linux easily has more than double the number
of readily available tools that are free
which reduce time scales for doing a project to a quarter
and less than any competing OS.

I can't seem to find a simple solution to this seemingly simple problem.
(I'm using Linux, in case there are no portable solutions.)
I need to determine whether a directory is currently used as a mount point.
(Because I need to run fsck on the underlying device, and running fsck on
a mounted file system is not safe.)
On Linux, rmdir returns EBUSY when its argument "is currently used as a
mount point, or is the root directory of the calling process."

I have to be able to read and receive data through an Ethernet port from and to a FPGA.
This data is supposed to be just streams of number. I´ve seen the code given in this url: http://www.mathworks.com/matlabcentral/fileexchange/27290-collect-and-plot-data-from-a-tcpip-server-in-real-time
And I have some questions.. about the IP address, can I set the one I prefer? and, how to send the information I have just received without doing anything with it?
Hope anyone can help me.
Thanks in advance
...Matlab ignores subfunction
I have a GUI that uses a fairly complex Buttondownfcn for one object.
Instead of putting it all inside of one sting, I decided to give the
whole procedure a name and call it as function at buttondown. As long
as I save this as a seperate file, it works fine. As soon as I
include it in the main function file, as a subfunction, Matlab
'??? Undefined function or variable 'track_on'.
??? Error while evaluating figure WindowButtonDownFcn.'
In order to give you a more complete idea of what's going on, the
whole script looks something like this:

I have the following data type:
data Expr =
| Add Expr Expr -- x + y
| Multipy Expr Expr -- x*y
| Power Expr Expr -- x^y
It represents an expression, which can consist of signed integer
literals (arbitrary size), and operators:
addition, multiplication, exponentiation. Semantically, this
expression may denote a complex number. If
an exponentiation is ambiguous, let it represent a complex number with
a minimal non-negative argument.
For instance, Power (Literal (-1)) (Power (Literal 2) (Literal (-1)))
represents I (the imaginary unit), not (-I).

I work for a company that has both matlab and flowmaster, and I am wondering if there is a way to get matlab to run flowmaster (similar to the way excel can run matlab).
According to matlab's website, simulink will run flowmaster (which means matlab should be able to as well) but there is no explanation of how to make that happen. I would prefer to avoid simulink if possible; I am more famaliar with matlab coding.
Does anyone have any examples of running flowmaster through matlab?
Is there an add-on required to do this? How do I know if I have that add-on?

Yes. In our application, Matlab forks and then execs to start a
child program. Then the two communicate on a frequent basis. Under
Windows we do something similar, only we use a spawn function

I have external software that I'd like to combine with MATLAB. I can
successfully call a non-GUI version of MATLAB that'll execute
whatever operations I want then send them back into the code. But
what I'd really like to do is have a full-blown version of MATLAB
running and just tell it to wait for data from the external program.
Once that data arrives I'd then have all those variables in my
workspace that I could play with.
I suppose I could use the disk as an intermediary but that seems
clunky to me and I'd have to go tell MATLAB to execute. I'd much
