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
-1
b
. Call a solver routine instead (see Solving Systems of Linear Equations); this is more efficient and more accurate.
