ssyconvf

Functions

void ssyconvf(
    const char*          uplo,
    const char*          way,
    const INT            n,

);

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

If parameter WAY = ‘C’: SSYCONVF converts the factorization output format used in SSYTRF 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.

It also converts in place details of the interchanges stored in IPIV from the format used in SSYTRF into the format used in SSYTRF_RK (or DSYTRF_BK).

If parameter WAY = ‘R’: SSYCONVF 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 that is stored on exit in parameter A. It also converts in place details of the interchanges stored in IPIV from the format used in SSYTRF_RK (or DSYTRF_BK) into the format used in SSYTRF.
