How to pass matrix as input to matlab function from .net app?

Question

I want to pass matrix as input from .net app to matlab function

Matlab function:

function myfunc(info);
   sort(info)
end

I want info input be recieved in function like this:

info = [...
            0   0   0;  ... 
            0   120 0;  ... 
            240 120 0;  ... 
            240 0   0;  ... 
            ];

and .net code:

MLApp.MLApp matlab = new MLApp.MLApp();

matlab.Execute(@"cd C:\scripts\myfunc.m");

object result = null;

int[,] input = new int[4, 3] { { 0, 0, 0 }, { 0, 120, 0 }, { 240, 120, 0 }, { 240, 0, 0 } };

matlab.Feval("myfunc", 0, out result, input);

This gives me error in Feval line--> "error using norm first argument must be single or double."

And when I change input to be like this

int[,,] input = new int[4, 1, 3] {
    { {0, 0, 0} },
    { {0, 120, 0} },
    { {240, 120, 0} },
    { {240, 0, 0} }
};

It gives another error --> 'index in position 1 exceeds array bounds. index must not exceed 1

How to solve this?
