Launch MCR in a C# code

Hello,

I would like to execute Matlab functions in a C# code (VS2010, W7). My C# code is as follows:

// Declaration

DllImport(@"C:\Program Files\MATLAB\MATLAB Compiler Runtime\v715 bin\win32\libeng.dll", CallingConvention = CallingConvention.Cdecl)]

static extern IntPtr engOpen(string startcmd);

// Call MCR

IntPtr engine = engOpen(null);

Matlab is launched but however crashs immediately without any log or information...

Any idea?

Thanks for your help!

Hi again,

Since you have an installed MATLAB and working with C#, why arent you using COM directly? This makes it a way easier:

And make sure MATLAB is registered as COM server. In order to register it run

regmatlabserver

in MATLAB.

Hi,

Thank you for your quick answer.

I also tried with the installed version of Matlab on my computer, i.e. the link to the libeng.dll is C:\Program Files\MATLAB\R2010a\bin\win32\libeng.dll

But I have the save behavior. I think there is another problem...?
