Hi,

I have Two questions regarding Matlab's Engine:

1. I've seen examples where the engine is used to find eigenvalues using engeval("D=eig(A*A')"). Suppose I have a function in Matlab called ComputeEigenValue(A), how can I call it using engval?

2. Suppose I wrote C code that uses the Matlab engine as part of a solution in Visual Studio. Can I compile it as usual from Visual Studio, or do I need to compile it from Matlab?

Thank you,

Gil.

So I'm trying to run a simple program following the tutorial:

http://www.mathworks.com/support/solutions/en/data/1-78077S/?solution=1-78077S

I got to section 4.d, but I'm not sure what to do. What's currently written under Under Configuration Properties->Debugging->Command is $(TargetPath). Do I need to replace it with C:\Program Files\MATLAB\R2010b\bin\win32 or with PATH= C:\Program Files\MATLAB\R2010b\bin\win32?

I tried both ways and I when I try to run the program, I get an error "unable to start program 'C:\Program Files\MATLAB\R2010b\bin\win32 The system cannot find the file specified.

Can someone please write what exactly I need to write under "Command"?

Thank you,

Gil.

在 MATLAB Online 中打开

engeval('Variable=ComputeEigenValue(A)');

I do not know about compilation.

I have another question regarding your answer - where should the function ComputEigenValue resise? how will the instance of Matlab will know about it?

Thank you,

Gil.
