...Embedded Matlab interface error : error calling MATLAB function 'sf'
I am using MATLAB 7.6 on a 64-bit machine.
I am trying to run a mathematical model containing various user defined embedded matlab function that was previously 'built and run' using same matlab version but on a 32-bit machine.
I am getting this error on my current machine setup "Embedded Matlab interface error : error calling MATLAB function 'sf'".
I have already visited many matlab central pages yet I am unable to find a solution to this specific problem.

...Calling Matlab functions from S-Functions in C...
I am trying to write an application in Simulink using S-Functions
written in C language. I would like to know if I could call Matlab
Array functions like 'var', 'median' etc from the S-Functions written
in C. i.e., Is there a C interface for the Matlab functions?
Any response would be appreciated.

I have an existing Matlab C MEX function (walkode.dll) that
returns state derivatives when called by ode23s
(walkode,...) from a regular Matlab script or the command
line. I would like to incorporate this into a Simulink
model, and have done so using a Level 1 M-file S-function,
which called walkode in the mdlDerivatives subfunction.
However this model runs very slowly.
I would prefer to rewrite (recompile?) my .dll as a C MEX S-
function (using sfuntmpl_doc.c I believe), but I am unsure
as how to go about doing so. This is where my understanding
(or more aptly, misunderstanding) of C,...Matlab
I'm trying to write code for the c2d function in Matlab - where the inputs are state matrices A, B, C, D, and a delta time-step. The outputs are [phi] and [gamma], the a and b matrices of the new, discrete state representation.
I'm not sure where to start. Can anyone offer any suggestions?

as it is described in this tutorial:
I have tried to do something similar in Visual Studio 2005 [Matlab 7,

Hi guys. I really apologize for asking this question, since I'm sure it is either basic or not possible, but I have been reading through the documentation and can't seem to figure this out, since the examples look like they just send and receive variables from the Java methods.
Could anyone give me a short example of how to call a method from a Java object that causes some sort of action to be performed in MATLAB?
For example, I would like to:
1) make a new object of MyClass from MATLAB called MyObject.
2) run MyObject.DoSomethingInMatlab()
3) have a statement in DoSomethingInMatlab...call to matlab function from matlab GUI stalls
I have the following problem. I have created a simple Matlab GUI (for
our purposes it can just be considered a Matlab function) which
gathers some parameters and then invokes a perl script that in turn
calls other perl and Matlab scripts to perform various calculations.
If instead of using the Matlab GUI, I run the perl command from the
unix prompt, the flow runs and concludes correctly.
BUT if I invoke the flow from the Matlab GUI (function), then it runs
correctly by calling various other perl and Matlab scripts, but then
when it reaches the third Matlab function call, it consistently
stalls...How to use matlab functions as callback functions in dll's?

...how to call a Matlab function from within a MEX function written in C?
I have a MEX function written in C, let's call it Afunc.cpp,
and I have another Matlab function called Bfunc.m (it is not from the
Mathworks, so it is not the pre-defined Matlab function)
Is it possible to call this Bfunc.m from within Afunc.cpp? It is because the
Bfunc.m is too complicated and it used a lot Matlab predefined function
which I don't how to rewrite in C/Cpp. So a simpler way for me is to let
Afunc.cpp call Bfunc.m...
How to do that? Thanks a lot!

I have one question: Is Matlab's 'graycomatrix' function actually in
accordance with original Haralick's 1973 paper?
I mean, are they supposed to be the same algorithm? If yes, I don't
think Matlab did a good job on this.
For example, try it on this matrix (i.e., 'image'):
0 0 1 1
0 0 1 1
0 2 2 2
2 2 3 3
This matrix is in Haralick's original paper and the results can be

Using MatLab's 'movie' function you can play a movie recorded by the
'getframe' command. It is possible to specify the number of times the
movie is played and the frames per second.
Unfortunately, I've not found a way to stop the playback of a movie.
Is it possible to, let's say I've specified the movie should be played
20 times, to disrupt the playback after an user interrupt?!
Thanks a lot,
