Function Documentation

core_clrmm_Cfr()

static pastix_fixdbl_t core_clrmm_Cfr ( core_clrmm_t *  params )

inlinestatic

Compute the matrix matrix product when applied to a full rank matrix.

This function considers that the C matrix is full rank, and A and B are either full-rank or low-rank. The result of the product is directly applied to the C matrix.

Parameters

[in,out]

params

The LRMM structure that stores all the parameters used in the LRMM functions family.

See also

core_clrmm_t

Returns

The number of flops required to perform the operation.

core_clrmm_Cnull()

static pastix_fixdbl_t core_clrmm_Cnull ( core_clrmm_t *  params )

inlinestatic

Compute the matrix matrix product when applied to a null matrix.

This function considers that the C matrix is null, and A and B are either full-rank or low-rank. The result of the product is directly applied to the C matrix.

Parameters

[in,out]
