Purpose
-------
CGEMM performs one of the matrix-matrix operations
C = alpha*op( A )*op( B ) + beta*C,
where op( X ) is one of
op( X ) = X or
op( X ) = X**T or
op( X ) = X**H,
alpha and beta are scalars, and A, B and C are matrices, with
op( A ) an m by k matrix, op( B ) a k by n matrix and C an m by n matrix.
Parameters
----------
@param[in]
transA magma_trans_t.
On entry, transA specifies the form of op( A ) to be used in
the matrix multiplication as follows:
- = MagmaNoTrans: op( A ) = A.
- = MagmaTrans: op( A ) = A**T.
- = MagmaConjTrans: op( A ) = A**H.
@param[in]
transB magma_trans_t.
On entry, transB specifies the form of op( B ) to be used in
the matrix multiplication as follows:
- = MagmaNoTrans: op( B ) = B.
- = MagmaTrans: op( B ) = B**T.
- = MagmaConjTrans: op( B ) = B**H.
@param[in]
m Array of integers, dimension (batchCount + 1)
On entry, each INTEGER M specifies the number of rows of the
corresponding matrices op( A ) and C. M must be at least zero.
The last element of the array is used internally by the routine.
@param[in]
n Array of integers, dimension (batchCount + 1).
On entry, each INTEGER N specifies the number of columns of the
corresponding matrix op( B ) and the number of columns of the
corresponding matrix C. N must be at least zero.
The last element of the array is used internally by the routine.
@param[in]
k Array of integers, dimension (batchCount + 1).
On entry, each INTEGER K specifies the number of columns of the
corresponding matrix op( A ) and the number of rows of the
corresponding matrix op( B ). K must be at least zero.
The last element of the array is used internally by the routine.
@param[in]
alpha COMPLEX
On entry, ALPHA specifies the scalar alpha.
@param[in]
dA_array Array of pointers, dimension (batchCount).
Each is a COMPLEX array A of DIMENSION ( LDDA, ka ), where ka is
K when transA = MagmaNoTrans, and is M otherwise.
Before entry with transA = MagmaNoTrans, the leading M by K
part of the array A must contain the matrix A, otherwise
the leading K by M part of the array A must contain the
matrix A.
@param[in]
ldda Array of integers, dimension (batchCount + 1).
On entry, each INTEGER LDDA specifies the first dimension of
the corresponding matrix A as declared in the calling (sub) program.
When transA = MagmaNoTrans then LDDA must be at least max( 1, M ),
otherwise ldda must be at least max( 1, K ).
The last element of the array is used internally by the routine.
@param[in]
dB_array Array of pointers, dimension (batchCount).
Each is a COMPLEX array B of DIMENSION ( LDDB, kb ), where kb is
N when transB = MagmaNoTrans, and is K otherwise.
Before entry with transB = MagmaNoTrans, the leading K by N
part of the array B must contain the matrix B, otherwise
the leading N by K part of the array B must contain the
matrix B.
@param[in]
lddb Array of integers, dimension (batchCount + 1).
On entry, each INTEGER LDDB specifies the first dimension of
the corresponding matrix B as declared in the calling (sub) program.
When transB = MagmaNoTrans then LDDB must be at least max( 1, K ),
otherwise LDDB must be at least max( 1, N ).
The last element of the array is used internally by the routine.
@param[in]
beta COMPLEX.
On entry, BETA specifies the scalar beta. When BETA is
supplied as zero then C need not be set on input.
@param[in,out]
dC_array Array of pointers, dimension (batchCount).
Each is a COMPLEX array C of DIMENSION ( LDDC, N ).
Before entry, the leading M by N part of the array C must
contain the matrix C, except when beta is zero, in which
case C need not be set on entry.
On exit, the array C is overwritten by the M by N matrix
( alpha*op( A )*op( B ) + beta*C ).
@param[in]
lddc Array of integers, dimension (batchCount + 1).
On entry, each INTEGER LDDC specifies the first dimension of
the corresponding matrix C as declared in the calling (sub) program.
LDDC must be at least max( 1, M ).
The last element of the array is used internally by the routine.
@param[in]
batchCount INTEGER
The number of matrices to operate on.
@param[in]
queue magma_queue_t
Queue to execute in.
