Dear all,

We try to access a third party Matlab dll (which was created using Matlab
COM Builder) from C#. It works fine when using strings and one-dimensional
arrays but fails with two-dimensional arrays. We give our example of the code
below:

static void TestBasicStat()
       {

           MatlabCOM pda = new MatlabCOM();
           Object mError = new int();
           Array TempTagValues = new double[10, 20];
           Object gaTagValues = new Object(); // This is the result from
Matlab. It should be a 2-dim array
           pda.basicstatistics(2, ref gaTagValues, ref            mError,
TempTagValues);  
       }

An exception is thrown from the Matlab code when Matlab tries to access the
two-dimensional array.

Does anyone know if a double array is the correct conversion to a Matlab
matrix?

Also, please let me know if this is not the right newsgroup to post for this
question.

Thank you in advance!

Best regards

Hakan
