Hi, I am reading the help documents about how to program matlab and C C++ together and my questions are a little bit general. It seems that are several ways to call matlab in C C++ and another several ways to call C C++ in matlab. Please correct me if I am wrong or missing something when I try to list them. To call matlab code in C C++, are there two methods available? The first one is Matlab engine and the second one is to use MATLAB Compiler mcc to create C or C++ shared libraries from your MATLAB code. To call C C++ in matlab, are there also two methods? The first one is to call funct...

Hi everybody! My problem can be described as follows. I have a tool in Matlab that requires calling an optimisation algorithm in C. This algorithm consists of several C-files, one of which contains the function to be minimised (CFUNCTION), and another is the main algorithm file (CMAIN). Now what I want to do is to call Matlab from CFUNCTION or CMAIN and specify my custom function (MFUNCTION) to be minimised. So, I'm calling Matlab from C from Matlab. I'm a newbie in C and MEX files. Should I rewrite CMAIN as a MEX file and include CFUNCTION in this and then use mxCallMATLAB? Or can...

I'm relatively new to the world of Matlab. I want to call my matlab own code from a C/C++ program on a machine with matlab installed.

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. To see the special character of C or C++ coding language, in the editor go to menus: file>preferences>Edito/Debugger>language and on popup "Language" select "C/C++". This does not allow you to run the C/C++ code, just to view it i nicer way... regards, chris saneman <asdfsdf@asd.com> wrote in message <frl846 $f8i$2@news.net.uni-c.dk>... > Is it possible to read C/C...

Hi, I am learning to call Matlab code from C/C++ code. Here are my questions (1)are using Matlab engine and converting Matlab code into a C or C++ shared library the only two ways?

Hiya, I'm writing c language code & I'd like to be able to integrate a number of matlab functions to my code. I've tried to do this with the visual studio add in, but it always generates errors. I'm able to compile c code with the matlab compiler, but whenever I try to call a matlab function this causes errors. How does one compile c++ code with matlab? And when I'm at it, how can standard c variable types(int, double...) be converted to matlab types (and in the opposite direstion too)? Thanks for your help ...

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.

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 man...

I am working on conversion of .m files to c/c++. I am using the MATLAB compiler version 3.0 and MATLAB version 6.5.1. There seem to be a few functions which do not seem to get converted. The error i got while using functions like TRAIN, NETWORK and INIT (all neural-networks related functions used in the general neural network programs, newpnn.m etc) is The MATLAB compiler does not currently support MATLAB object oriented programming and the functions TRAIN , NETWORK and INIT would produce a run-time error.

Hi, In my project, I need to call a Matlab function in some C# code. I compiled the Matlab code into a dll and have included that into my C# project. However, I have some problems in figuring out what C# data types correspond to the data types I used in my Matlab code. Specifically, I have an array of struct in Matlab code, i.e. x(j) = c, and c is a struct, having c.a and c.b. I also have a multi-layer struct, something like lmcoords.goalyellow.left.x = -0.67; lmcoords.goalyellow.left.y = -3; lmcoords.goalyellow.right.x = 0.67; lmcoords.goalyellow.right.y = -3; Basically I want to find...

Yes, effectively so. A\b in MATLAB uses UMFPACK, CHOLMOD, MA57, a sparse QR by John Gilbert, and other specialized solvers (such as handling the case when A is lower triangular, or when A is banded with a density in the band that's high enough to warrant the use of LAPACK's band solvers). Most of these codes are readily available. MA57 requires a license; it's in the Harwell Subroutine Library. I don't have a copy of Gilbert's sparse QR, but I do...
