methods to call matlab in C C++ and call C C++ in matlab
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...

How to call matlab functions directly from C++ /without calling matlab engine
How to call matlab functions directly from C++ without calling matlab engine. as it is described in this tutorial: http://www.codeproject.com/samples/matlab_cpp.asp I have tried to do something similar in Visual Studio 2005 [Matlab 7, r14] #include <mclcppclass.h> .... mwArray A, B, C; A = magic(mwArray(5)); B = transpose(A); .... but it doesn't compile. I got following errors: error C3861: 'magic': identifier not found error C3861: 'transpose': identifier not found etc...

C/C++ in matlab and matlab in C/C++ ?
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...

Conversion from MATLAB to C/C++ using MATLAB compiler
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. Could anyone please tell me as to how i can circumnavigate this problem or solve this...

matlab calling DLL vs. .exe calling matlab engine
Hello, I'm writing an 3D image recognition which sends commands via RS232 to a Robot which moves to the point in 3D. The problem is the serial interface: sending string commands via serial/fprintf is very slow (I really don't know what matlab makes before sending them) in comparison to e.g. Windows hyperterminal. My question is if it is better to execute a dll out of Matlab-code doing the serial things or viceversus writing a program in c++ which uses the matlab-engine ? What could be the fastest way? What are advantages/disadvantages ? Any help would be appreciated. Thanks in advanc...

Calling Matlab Engine from C
Hi I have a code written in C. I want to call a matlab's M-file from this C code. I have already successfully executed the sample 'engdemo.c' file. what i am unable to do is to make matlab engine run this 'Load.m' file directly when it opens without me having to type in the code in the matlab command window. How can i make this happen? How to pass the name of the M-file which i want MATLAB to execute? Please help if you can!! Thanks in advance.

Incremental saving of matfiles using matlab engine and matrix library with c/c++
Hi, I am using the matlab engine and matrix library to save simulated data out of a c++ project into a mat file. The simulated data includes several structures with several fields. The problem is, that the simulation produces a large amount of data so the memory is too small to store this data to the end of the simulation and save it into a mat file. Is it possible to store the simulated data incrementally in a mat file. For example every n simulation cycles? Actually I produce sub mat files, but this is only a work around. Regards, Andreas ...

calling sas using matlab (or conditional deletion in matlab)
my issue: i only need data past a certain date for a large number of time series. is this possible in matlab? i have been toying around with different ways, and found one solution (descending sort paired with a conditional statement). for example if x(i)<datenum(1/1/2006,'mm/dd/yyyy') then delete else keep ....etc i know this is not matlab code, but it explains my goal. but, i would prefer a more concise way of executing this step. with this, is there any way to call sas code with matlab? (makes parsing data obviously much more concise). any input would be greatly appreciated. ...

vectorized computation in C++ such as those in Matlab (Matlab to C++)?
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...
