use MATLAB function in C#

I have a MATLAB function which get a numeric array and return same sized array. I compiled it with Builder NE and I use this function in C# code. I can pass to the function a double array without problems, but an int array cause some problems. To convert C# array to MATLAB type array I use MWNumericArray() class, which has a bool MakeDouble argument, but it unusable with array (just with scalar). Is there any option to pass an int array to the function without convert to double array?

Please explain what you mean by "an int array cause some problems" - what is the exact symptom? Do you see an error, if yes, paste the exact error message.
