That is, given the matrix A, solve the matrix system AX = I Any solver that handles complex matrix right hand sides will do this for you. Iterative calls to a solver with successive columns of I can also be used to fill in columns of X. But I strongly recommend you rethink the approach. There are very few cases were inverting a matrix is a good idea.
