void ssyconvf_rook(const char *uplo, const char *way, const INT n, f32 *restrict A, const INT lda, f32 *restrict E, const INT *restrict ipiv, INT *info)#

If parameter WAY = ‘C’: SSYCONVF_ROOK converts the factorization output format used in SSYTRF_ROOK provided on entry in parameter A into the factorization output format used in SSYTRF_RK (or DSYTRF_BK) that is stored on exit in parameters A and E.

IPIV format for SSYTRF_ROOK and SSYTRF_RK (or DSYTRF_BK) is the same and is not converted.

If parameter WAY = ‘R’: SSYCONVF_ROOK performs the conversion in reverse direction, i.e. converts the factorization output format used in SSYTRF_RK (or DSYTRF_BK) provided on entry in parameters A and E into the factorization output format used in SSYTRF_ROOK that is stored on exit in parameter A. IPIV format for SSYTRF_ROOK and SSYTRF_RK (or DSYTRF_BK) is the same and is not converted.
