Hi,
There are a few data type mapping rules for converting .NET data types to MATLAB types using MWArray class hierarchy. You can use MWNumericArray to create the type of array you showed above. It can be done in C# as follows:
MWNumericArray output = new MWNumericArray(new int[] { 3, 2, 2 });
To read more about MWarray and its types, you can refer to the document: http://www.mathworks.com/help/dotnetbuilder/MWArrayAPI/HTML/index.html
Also, there is another example that illustrates the usage of types of MWarray: http://www.mathworks.com/matlabcentral/answers/91689-is-there-an-example-of-using-the-mwarray-data-type-in-a-net-language-such-as-c-with-a-matlab-bui
