EvaluateFunction error .. fails with no error message

Hi there, Trying to make a call to a function in a MATLAB assembly built by MATLAB BUILDER NE ,for .Net, an exception is thrown without any messages :

MWMCR::EvaluateFunction error ...

   at MathWorks.MATLAB.NET.Utility.MWMCR.EvaluateFunction(String functionName, Int32 numArgsOut, Int32 numArgsIn, MWArray[] argsIn)
   at MathWorks.MATLAB.NET.Utility.MWMCR.EvaluateFunction(Int32 numArgsOut, String functionName, MWArray[] argsIn)
   at ...

The function that is tried to call is a rather simple MATLAB function that calls another one.

The following peices of software has been installed: MATLAB R2009a (64 bit) Microsoft Visual Studio 2008

Any suggestion will be appreciated.

Are you sure there is no error message displayed after "MWMCR::EvaluateFunction error ..."? Typically the accompanying message gives us a hint to exactly why there was a failure in evaluation of the compiled function.

Also, do you add the other function (that is called from the main function) to "Additional/Other Files" in deploytool?

Hi Kaustubha Thanks for the comment. For you and other viewers' info: It was strange but, there was a line in one of functions : addpath(genpath(MainFolder)); I removed it, and added the 'MainFolder' folder path (and its subfolders), manually.

And it is solved now. No exception, No error.

Do you mean that you added the folder to "Additional/Other Files" in deploytool?

Note that this is the correct way to do it rather than using "addpath", because the compiled assembly only has access to the user-defined functions that have been added to the CTF archive.
