Parameter Description

Parameter	Description
trans_a	Int, whether matrix A is transposed.
trans_b	Int, whether matrix B is transposed.
trans_c	Int, whether matrix C is transposed. Currently, only aclTrans_N is supported.
m	Int, number of rows in matrix A and matrix C.
n	Int, number of columns in matrix B and matrix C.
k	Int, number of columns in matrix A and number of rows in matrix B.
type	Int, computation precision.

Return Value Description

Return Value	Description
handle	Int, pointer address of the handle data of the operator to be executed.
ret	Int, error code: 0 on success; else, failure.
