Purpose
=======
sp_c 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' or op( X ) = conjg( X' ),
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
==========
TRANSA - (input) char*
On entry, TRANSA specifies the form of op( A ) to be used in
the matrix multiplication as follows:
TRANSA = 'N' or 'n', op( A ) = A.
TRANSA = 'T' or 't', op( A ) = A'.
TRANSA = 'C' or 'c', op( A ) = conjg( A' ).
Unchanged on exit.
TRANSB - (input) char*
On entry, TRANSB specifies the form of op( B ) to be used in
the matrix multiplication as follows:
TRANSB = 'N' or 'n', op( B ) = B.
TRANSB = 'T' or 't', op( B ) = B'.
TRANSB = 'C' or 'c', op( B ) = conjg( B' ).
Unchanged on exit.
M - (input) int
On entry, M specifies the number of rows of the matrix
op( A ) and of the matrix C. M must be at least zero.
Unchanged on exit.
N - (input) int
On entry, N specifies the number of columns of the matrix
op( B ) and the number of columns of the matrix C. N must be
at least zero.
Unchanged on exit.
K - (input) int
On entry, K specifies the number of columns of the matrix
op( A ) and the number of rows of the matrix op( B ). K must
be at least zero.
Unchanged on exit.
ALPHA - (input) singlecomplex
On entry, ALPHA specifies the scalar alpha.
A - (input) SuperMatrix*
Matrix A with a sparse format, of dimension (A->nrow, A->ncol).
Currently, the type of A can be:
Stype = NC or NCP; Dtype = SLU_C; Mtype = GE.
In the future, more general A can be handled.
B - COMPLEX PRECISION array of DIMENSION ( LDB, kb ), where kb is
n when TRANSB = 'N' or 'n', and is k otherwise.
Before entry with TRANSB = 'N' or 'n', 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.
Unchanged on exit.
LDB - (input) int
On entry, LDB specifies the first dimension of B as declared
in the calling (sub) program. LDB must be at least max( 1, n ).
Unchanged on exit.
BETA - (input) singlecomplex
On entry, BETA specifies the scalar beta. When BETA is
supplied as zero then C need not be set on input.
C - COMPLEX PRECISION array of DIMENSION ( LDC, 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 )*B + beta*C ).
LDC - (input) int
On entry, LDC specifies the first dimension of C as declared
in the calling (sub)program. LDC must be at least max(1,m).
Unchanged on exit.
