Detailed Description
BLAS Level 3 API.
trmm performs one of the matrix-matrix operations
B := alpha*op( A )*B, or B := alpha*B*op( A )
where alpha is a scalar, B is an m by n matrix, A is a unit, or non-unit, upper or lower triangular matrix and op( A ) is one of
op( A ) = A or op( A ) = A^T or op( A ) = A^H.
When uplo == rocblas_fill_upper the leading k by k upper triangular part of the array A must contain the upper triangular matrix and the strictly lower triangular part of A is not referenced. Here k is m when side == rocblas_side_left and is n when side == rocblas_side_right.
When uplo == rocblas_fill_lower the leading k by k lower triangular part of the array A must contain the lower triangular matrix and the strictly upper triangular part of A is not referenced. Here k is m when side == rocblas_side_left and is n when side == rocblas_side_right.
Note that when diag == rocblas_diagonal_unit the diagonal elements of A are not referenced either, but are assumed to be unity.
- Parameters
-
[in] handle [rocblas_handle] handle to the rocblas library context queue. [in] side [rocblas_side] Specifies whether op(A) multiplies B from the left or right as follows: rocblas_side_left: B := alpha*op( A )*B. rocblas_side_right: B := alpha*B*op( A ). [in] uplo [rocblas_fill] Specifies whether the matrix A is an upper or lower triangular matrix as follows: rocblas_fill_upper: A is an upper triangular matrix. rocblas_fill_lower: A is a lower triangular matrix. [in] transA [rocblas_operation] Specifies the form of op(A) to be used in the matrix multiplication as follows: rocblas_operation_none: op(A) = A. rocblas_operation_transpose: op(A) = A^T. rocblas_operation_conjugate_transpose: op(A) = A^H. [in] diag [rocblas_diagonal] Specifies whether or not A is unit triangular as follows: rocblas_diagonal_unit: A is assumed to be unit triangular. rocblas_diagonal_non_unit: A is not assumed to be unit triangular. [in] m [rocblas_int] m specifies the number of rows of B. m >= 0. [in] n [rocblas_int] n specifies the number of columns of B. n >= 0. [in] alpha alpha specifies the scalar alpha. When alpha is zero then A is not referenced and B need not be set before entry. [in] A Device pointer to matrix A on the GPU. A has dimension ( lda, k ), where k is m when side == rocblas_side_left and is n when side == rocblas_side_right. [in] lda [rocblas_int] lda specifies the first dimension of A. if side == rocblas_side_left, lda >= max( 1, m ), if side == rocblas_side_right, lda >= max( 1, n ). [in,out] B Device pointer to the first matrix B_0 on the GPU. On entry, the leading m by n part of the array B must contain the matrix B, and on exit is overwritten by the transformed matrix. [in] ldb [rocblas_int] ldb specifies the first dimension of B. ldb >= max( 1, m ).
