Function Documentation

◆ core_dlrmm_Cfr()

static pastix_fixdbl_t core_dlrmm_Cfr ( core_dlrmm_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]paramsThe LRMM structure that stores all the parameters used in the LRMM functions family.
See also
core_dlrmm_t
Returns
The number of flops required to perform the operation.

◆ core_dlrmm_Cnull()

static pastix_fixdbl_t core_dlrmm_Cnull ( core_dlrmm_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]paramsThe LRMM structure that stores all the parameters used in the LRMM functions family.
