Purpose
=======
CTRMM 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' or op( A ) = conjg( A' ).
Parameters
==========
@param[in]
side magma_side_t.
On entry, side specifies whether op( A ) multiplies B from
the left or right as follows:
side = magmaLeft B := alpha*op( A )*B.
side = magmaRight B := alpha*B*op( A ).
Unchanged on exit.
@param[in]
uplo magma_uplo_t.
On entry, uplo specifies whether the matrix A is an upper or
lower triangular matrix as follows:
uplo = magmaUpper A is an upper triangular matrix.
uplo = magmaLower A is a lower triangular matrix.
Unchanged on exit.
@param[in]
transA magma_trans_t.
On entry, transA specifies the form of op( A ) to be used in
the matrix multiplication as follows:
transA = MagmaNoTrans op( A ) = A.
transA = MagmaTrans op( A ) = A'.
transA = MagmaConjTrans op( A ) = conjg( A' ).
Unchanged on exit.
@param[in]
diag magma_diag_t.
On entry, diag specifies whether or not A is unit triangular
as follows:
diag = MagmaUnit A is assumed to be unit triangular.
diag = MagmaNonUnit A is not assumed to be unit
triangular.
Unchanged on exit.
@param[in]
m INTEGER array, dimension(batchCount + 1).
On entry, each integer M specifies the number of rows of the corresponding
matrix B. M must be at least zero.
Unchanged on exit.
@param[in]
n INTEGER array, dimension(batchCount + 1).
On entry, each integer n specifies the number of columns of the corresponding
matrix B. N must be at least zero.
Unchanged on exit.
@param[in]
alpha DOUBLE COMPLEX.
On entry, alpha specifies the scalar alpha. When alpha is
zero then A is not referenced and B need not be set before
entry.
Unchanged on exit.
@param[in]
dA_array Array of pointers, dimension(batchCount).
Each is a DOUBLE COMPLEX array A of DIMENSION ( ldda, k ), where k is M
when side = magmaLeft and is N when side = magmaRight.
Before entry with uplo = magmaUpper, 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.
Before entry with uplo = magmaLower, 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 = MagmaUnit, the diagonal elements of
A are not referenced either, but are assumed to be unity.
Unchanged on exit.
@param[in]
ldda INTEGER array, dimension(batchCount + 1).
On entry, ldda specifies the first dimension of A as declared
in the calling (sub) program. When side = magmaLeft then
ldda must be at least max( 1, M ), when side = magmaRight
then ldda must be at least max( 1, N ).
Unchanged on exit.
@param[in,out]
dB_array Array of pointers, dimension(batchCount).
Each is a DOUBLE COMPLEX array B of DIMENSION ( lddb, N ).
Before 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]
lddb INTEGER array, dimension(batchCount + 1).
On entry, lddb specifies the first dimension of B as declared
in the calling (sub) program. lddb must be at least
max( 1, M ).
Unchanged on exit.
@param[in]
batchCount INTEGER.
The number of matrices to operate on.
@param[in]
queue magma_queue_t.
Queue to execute in.
