The Symbolic Math Toolbox contains the function 'inv' which will find the symbolic inverse of your matrix.
Or, if the values of your 12 constants are known, you can use the regular matlab function of the same name, 'inv'.

Hassan - if you are looking for the algorithm to determine the 4x4 matrix inverse, then see the notes from http://www.euclideanspace.com/maths/algebra/matrix/functions/inverse/fourD/index.htm which you can then update given your above matrix.
