Matrix Inversion: ScaLAPACK Computational Routines

This sections describes ScaLAPACK routines that compute the inverse of a matrix based on the previously obtained factorization. Note that it is not recommended to solve a system of equations Ax = b by first computing A-1 and then forming the matrix-vector product x = A-1b. Call a solver routine instead (see Solving Systems of Linear Equations); this is more efficient and more accurate.
