Hi all, I'm going to work on a project involving a parallel version of MATLAB - I'm aware of various efforts like MATLAB-*P and so on Right now I need to read up on some material regarding MATLAB internals eg: How are the ATLAS(or is it BLAS) routines called in MATLAB? How does MATLAB's C code store information in memory, cache'ing etc? How is one to get at those? Do you know of any suitable reference(s)/resource(s)? Thank you very much, Aravind ...

I'm making an end-user application where I would like to use Matlab functionality both for calculation and plotting. Matlabs GUI builder guide does not satisfy my needs (no support for f.ex. internal frames and other nescessities), so I'm planning to compile my Matlab code and use other API (Java, QT or something) for GUI. My problem is then, that I loose access to the neat plotting commands availible under matlab GUI... Is there a way of integrating Matlabs plot functionality into another GUI system? - has it been done? - I appreciate any response! - P�l Berge ...

Hello everyone, How do I compile MATLAB M files into a form that can then be called from within the MATLAB interpreter? A roundabout way would seem to be to (somehow) Turn the matlab code into C (I think mcc does this), then compile this C code into MEX format and call that. Is there an easier way? I have the MATLAB compiler, so I just need to know what to do with it to get this to work.

I am looking for information here on the MathWorks website about the changes between MATLAB 6 and MATLAB 7. Specifically, I am looking for information about changes in the handling of .mat files. For example if I have a mat-file: example.mat located in the MATLAB current directory. In MATLAB 7 I can load this data-file into the MATLAB workspace with: >> load example And it loads fine. If I type the above load command in MATLAB 6 I get and error. Is there anything that provides the technical information for this? Thanks Dave Dave wrote: > I am looking for information here on t...

Hi! Is it posible to make a Daemon in MATLAB so that i can access a shared memory between MATLAB and .NET? I ask this because every method i've tryied to call MATLAB functions from .NET are really slow, mostly the call process (because i call the function about 300.000-1.000.000 times in a small time lapse. I thought that using a Daemon using shared memory between my .NET app and MATLAB would make that performance bottleneck almost dissapear. Any other ideas are really appreciated. By the way, is it posible to open a socket in MATLAB? That would be another possible solution, less performa...

I am trying to execute some code (a mixture of C++ and Matlab) that was delivered to me. The Matlab code was originally developed under Matlab R14. I have Matlab R2006b installed on my system.

Hint: Check for a misconfigured environment or installation. When I look in the referenced directory, there does appear to be an ICU related .dat file. Any ideas as to what could be causing this runtime warning? Thanks. ...

Is it possible to read C/C++ code in matlab and the other way around too? Hi, as long as C or C++ are written in text files you can edit them in the matlab editor.

Dear all, Can C++/STL/Boost do the vectorized calculation as those in Matlab? For example, in the following code, what I really want to do is to send in a vector of u's. All other parameters such as t, l1, l2, l3, etc. are scalars... But u is a vector. Thus, t6 becomes a vector. t9 is an element-wise multiplication... The following code was actually converted from Matlab. If vectorized computation is not facilitated, then I have to call this function millions of times. But if vectorized computation is okay, then I can send in just a u vector with batch elements a time. I have many such code in Matlab need to be converted into C++ with vectorization. Any thoughts? Thank you! double t5, t6, t7, t9, t11, t13, t16, t20, t23, t27, t32, t34, t36, t37, t38, t42, t44, t47, t48, t51, t52, t54, t59, t60, t61, t66, t67, t69, t74, t75, t76, t81, t82, t84, t87, t105, t106, t110, t112; t5 = exp(-t * l1 - t * l2 - t * l3); t6 = t * u; t7 = mu1 * mu1; t9 = u * u; t11 = kappa * kappa; t13 = 0.1e1 / (t9 * t7 + t11); > Dear all, > > Can C++/STL/Boost do the vectorized calculation as those in Matlab? > > For example, in the following code, what I really want to do is to > send in a vector of u's. > > All other parameters such as t, l1, l2, l3, etc. are scalars... > > But u is a vector. > > Thus, t6 becomes a vector. > > t9 is an element-wise multiplication... > > The following code was actually converted f...
