Detailed Description
BLAS Level 3 API.
trmm_outofplace_strided_batched performs one of the strided_batched matrix-matrix operations
C_i := alpha*op( A_i )*B_i, or C_i := alpha*B_i*op( A_i ) for i = 0, 1, ... batch_count -1
where alpha is a scalar, B_i is an m by n matrix, A_i is a unit, or non-unit, upper or lower triangular matrix and op( A_i ) is one of
op( A_i ) = A_i or op( A_i ) = A_i^T or op( A_i ) = A_i^H.
Note that trmm_outofplace_strided_batched can provide in-place functionality in the same way as trmm_strided_batched by passing in the same address for both matrices B and C.
- Parameters
-
[in] handle [rocblas_handle] handle to the rocblas library context queue. [in] side [rocblas_side] Specifies whether op(A_i) multiplies B_i from the left or right as follows: rocblas_side_left: C_i := alpha*op( A_i )*B_i. rocblas_side_right: C_i := alpha*B_i*op( A_i ). [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_i) to be used in the matrix multiplication as follows: rocblas_operation_none: op(A_i) = A_i. rocblas_operation_transpose: op(A_i) = A_i^T. rocblas_operation_conjugate_transpose: op(A_i) = A_i^H. [in] diag [rocblas_diagonal] Specifies whether or not A_i is unit triangular as follows: rocblas_diagonal_unit: A_i is assumed to be unit triangular. rocblas_diagonal_non_unit: A_i is not assumed to be unit triangular. [in] m [rocblas_int] m specifies the number of rows of B_i. m >= 0. [in] n [rocblas_int] n specifies the number of columns of B_i. n >= 0. [in] alpha alpha specifies the scalar alpha. When alpha is zero then A_i is not referenced and B_i need not be set before entry. [in] A Device pointer to the first matrix A_0 on the GPU. Each A_i is of dimension ( lda, k ), where k is m when side == rocblas_side_left and is n when side == rocblas_side_right.
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.
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.
Note that when diag == rocblas_diagonal_unit the diagonal elements of A_i are not referenced either, but are assumed to be unity.
- Parameters
-
[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] stride_A [rocblas_stride] stride from the start of one matrix (A_i) and the next one (A_i+1) [in] B Device pointer to the first matrix B_0 on the GPU. [in] ldb [rocblas_int] ldb specifies the first dimension of B_i. ldb >= max( 1, m ). [in] stride_B [rocblas_stride] stride from the start of one matrix (B_i) and the next one (B_i+1) [out] C Device pointer to the first matrix C_0 on the GPU. [in] ldc [rocblas_int] ldc specifies the first dimension of C_i. ldc >= max( 1, m). [in] stride_C [rocblas_stride] stride from the start of one matrix (C_i) and the next one (C_i+1) [in] batch_count [rocblas_int] number of instances i in the batch.
