You may try to make the matrix into a Row Echelon form. This is similar to a technique of manually finding the matrix inverse https://en.wikipedia.org/wiki/Row_echelon_form
I'm not sure if MATLAB communications toolbox has any function for this operation. But worth checking http://www.mathworks.com/products/communications/
