I intend to work with OpenCV 1.1 version and Matlab2011 together. The program uses call to load library. However, it returns an error
> In loadlibrary at 347
In Untitled at 4
Error using loadlibrary (line 421)
There was an error loading the library "C:\Program Files
(x86)\OpenCV1.1\bin\cxcore110.dll"
C:\Program Files (x86)\OpenCV1.1\bin\cxcore110.dll is not a valid
Win32 application.
I have tested the program in Matlab 2008 and 2010 where it gives error of a different kind I have installed x64 Compilers and Tools and my system has Visual Studio2008 and 2010 with SDK7 and 6.1. Also, on doing MEX setup I get the following options
Select a compiler:
[1] Microsoft Software Development Kit (SDK) 7.1 in c:\Program Files (x86)\Microsoft Visual Studio 10.0
[2] Microsoft Visual C++ 2010 Express in c:\Program Files (x86)\Microsoft Visual Studio 10.0
[0] None
Compiler: 2
This also returns the error
Error in ==> untitled at 5
loadlibrary(...
I am perplexed at what to do as this problem is persistently appearing. I even followed the thread in link where tit mentions that 2011 supports load library. So,why does it not work?Please help.
Applications compiled for 32bits don't mix with applications compiled for 64bits. If your OpenCV was compiled for 32bits, make sure Matlab is 32bits as well as your compilers.
BTW, seriously consider moving to a more recent version. OpenCV 1.1 is jurassic!

I tried compiling .c files to .mex , everything goes well and mex files are created but still it gives me the following errors. can anybody explain what is .exp file and why its giving me error?

MEX completed successfully.
This problem may be caused by the different version of the C++ compiler.
I solved this problem by chooseing the C++ 2010 compiler.
To setup the compiler, type "mex -setup" first then type "mex -setup:I:\matlab2014b_win7\installation(root of your matlab installation)\bin\win64\mexopts\msvc2010.xml"
MEX configured to use 'Microsoft Visual C++ 2012 (C)' for C language compilation.

To choose a different C compiler, select one from the following:

i try to use SPArse Modeling Software [ Version: 2.5,matlab interface ], it need to compiler first.so i run the compiler.m in MATLAB 2012b .but it goes wrong.
Here is the log
>> compile

Use mex -setup to configure your environment properly.

I guess the problem is the MATLAB 2012b mismatching the compiler in PC.
And I try to use visual studio 2013 as my the default C compiler for MATLAB 2012b.
when i using the mex -setup command.
only two choice as follow ,and do not see the visual studio 2013 compiler.
Select a compiler:
[1] Microsoft Software Development Kit (SDK) 7.1 in C:\Program Files (x86)\Microsoft Visual Studio 10.0

I know MATLAB 2014b can use visual studio 2013 C compiler.
But how the lower version MATLAB to use high edition visual studio C compiler.
Someone else encountered this problem ?
My OS is windows 7 X64 , visual studio 2013 PRO, MATLAB 2012b.
I reference this ,but seems did't work.
Using Visual Studio 2013's C compiler for MATLAB
The compiler you are trying to use is not supported by your matlab version, you have to use one of the supported compilers.
I have a problem with my r2013a Matlab.
I want to protect a model using Simulink.ModelReference.protect('test') command. For this
I have to configure my compiler. I'm using the mex -setup command, and the xpcsetCC -setup command.
At first, Matlab says that is all ok with the compiler, but when i try to execute the Simulink.ModelReference.protect('model') command it shows an erro saying that there is no compiler avaiable.
Here are the sequences of commands:

I've already tried all different choices of available compilers. I also tried to choose no for the fist question of mex -setup ("Would you like mex to locate installed compilers [y]/n?") and choose the compiler manually. None of this worked.
I am trying to use MEX. I use MATLAB R2011a and my compiler is
Microsoft Visual C++ 2010 in C:\Program Files (x86)\Microsoft Visual Studio 10.0
I use this simple file:
http://www.shawnlankton.com/2008/03/getting-started-with-mex-a-short-tutorial/
and helloworld.cpp works, but demo.cpp does not. I either get a "out of memory" error, or MATLAB just crashes...
Appreciate any assistance.
this is the session of building exe file in matlab 7.1.
I think I have a problem with the compiler.

if the problem is with the compiler, how can I install another compiler?
I have windows 7 (64 bits) and I want that the exe file will work on windows operating system.
This is probably the result of one of two issues.
1) You don't have the Windows SDK installed (as indicated in the error message). According to this MathWorks page regarding supported compilers
Both Microsoft Visual Studio 2008 and Windows Software Development Kit (SDK) 6.1 must be installed. When installing Microsoft Visual Studio, you must choose "X64 Compilers and Tools" when installing Microsoft Visual Studio; this is not selected by default.
Now, keep in mind, this reference is for the most recent release of MATLAB, but I'm betting that this information is still relevant to your issue.
You can download the SDK here.
2) It's also possible that the compiler that you're using simply isn't supported for your release of MATLAB. See here for info on supported compilers for MATLAB 7.1.
