Detailed Description

BLAS Level 3 API
\details
trmm_batched performs one of the batched matrix-matrix operations
B_i := alphaop( A_i )B_i, or B_i := alphaB_iop( 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.
@param[in]
handle [rocblas_handle]
handle to the rocblas library context queue.
@param[in]
side [rocblas_side]
Specifies whether op(A_i) multiplies B_i from the left or right as follows:
rocblas_side_left: B_i := alphaop( A_i )B_i.
rocblas_side_right: B_i := alphaB_iop( A_i ).
@param[in]
uplo [rocblas_fill]
Specifies whether the matrix A is an uppoer or lower triangular matrix as follows:
rocblas_fill_upper: A is an upper triangular matrix.
rocblas_fill_lower: A is a lower triangular matrix.
@param[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.
@param[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.
@param[in]
m [rocblas_int]
m specifies the number of rows of B_i. m >= 0.
@param[in]
n [rocblas_int]
n specifies the number of columns of B_i. n >= 0.
@param[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.
@param[in]
A Device array of device pointers storing each matrix A_i 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.
@param[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 ).
@param[in]
B device array of device pointers storing each matrix B_i on the GPU.
On entry, the leading m by n part of the array B_i must
contain the matrix B_i, and on exit is overwritten by the
transformed matrix.
@param[in]
ldb [rocblas_int]
ldb specifies the first dimension of B_i. ldb >= max( 1, m ).
@param[in]
batch_count [rocblas_int]
number of instances i in the batch.
