f07fwc computes the inverse of a complex Hermitian positive definite matrix
, where
has been factorized by
f07frc.
f07fwc is used to compute the inverse of a complex Hermitian positive definite matrix
, the function must be preceded by a call to
f07frc, which computes the Cholesky factorization of
.
The computed inverse
satisfies

Please consult the
X06 Chapter Introduction for information on how to control and interrogate the OpenMP environment used within this function. Please also consult the
Users' Note for your implementation for any additional implementation-specific information.
The real analogue of this function is
f07fjc.
This example computes the inverse of the matrix
, where
Here
is Hermitian positive definite and must first be factorized by
f07frc.
