Improves the computed solution to a complex Hermitian positive definite system of linear equations AX=B, where A is held in packed storage, and provides forward and backward error bounds for the solution. (Computational routine.). [C version of LAPACK routine, converted from Fortran by f2c.]. Classes : D2d1b . Solution of systems of linear equations, including matrix inverses, and LU and related factorizations (complex Hermitian positive definite matrices) Type : C subroutine in CLAPACK package. Access : Public domain. Portable. Precision: Single. Note : For best results, CLAPACK developers prefer that you download and install the entire CLAPACK library on your system. To do this, see the netlib CLAPACK distribution for details. Usage : int cpprfs_(char *uplo, integer *n, integer *nrhs, complex * ap, complex *afp, c omplex *b, integer *ldb, complex *x, integer *ldx, real *ferr, real *berr, com plex *work, real *rwork, integer *info) Details : Fullsource Readme Source Utilities Sites : (1) NETLIB
