Detailed Description

BLAS Level 3 API
\details
trmm performs one of the matrix-matrix operations
B := alphaop( A )B, or B := alphaBop( 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.
@param[in]
handle [rocblas_handle]
handle to the rocblas library context queue.
@param[in]
side [rocblas_side]
Specifies whether op(A) multiplies B from the left or right as follows:
rocblas_side_left: B := alphaop( A )B.
rocblas_side_right: B := alphaBop( A ).
@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) 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.
@param[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.
@param[in]
m [rocblas_int]
m specifies the number of rows of B. m >= 0.
@param[in]
n [rocblas_int]
n specifies the number of columns of B. n >= 0.
@param[in]
alpha
alpha specifies the scalar alpha. When alpha is
zero then A is not referenced and B need not be set before
entry.
@param[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.
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 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 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.
@param[in]
ldb [rocblas_int]
ldb specifies the first dimension of B. ldb >= max( 1, m ).
