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

Calling Matlab in C in MatlabHi 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...

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...

calling Matlab code from C/C++ codeHi,
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?
(2) what's the difference between these two methods? Advantages and
disadvantages? In what case use which method is better?
Thanks and regards!

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

Calling Compiled MATLAB from MATLABHello 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.
Thanks in advance,
Sina

pseudo code is useful to obfuscate code - protect algorithms, yet
still run at full speed and be distributable to other matlab users

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.

1) a matlab script A calls a mex function B based upon fortran source code
2) mex function B calls another function in matlab C within matlab engine
3) matlab routine C calls another mex file in fortran D

a run-time error.

calling Matlab code in C#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;

Oops, I forgot to mention. There are multiple clients querying the server,

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...
