|
|
kusano |
7d535a |
=======
|
|
kusano |
7d535a |
sp_d performs one of the matrix-matrix operations
|
|
kusano |
7d535a |
C := alpha*op( A )*op( B ) + beta*C,
|
|
kusano |
7d535a |
where op( X ) is one of
|
|
kusano |
7d535a |
op( X ) = X or op( X ) = X' or op( X ) = conjg( X' ),
|
|
kusano |
7d535a |
alpha and beta are scalars, and A, B and C are matrices, with op( A )
|
|
kusano |
7d535a |
an m by k matrix, op( B ) a k by n matrix and C an m by n matrix.

kusano |
7d535a |
the matrix multiplication as follows:
|
|
kusano |
7d535a |
TRANSA = 'N' or 'n', op( A ) = A.
|
|
kusano |
7d535a |
TRANSA = 'T' or 't', op( A ) = A'.
|
|
kusano |
7d535a |
TRANSA = 'C' or 'c', op( A ) = conjg( A' ).
|
|
kusano |
7d535a |
Unchanged on exit.
|
|
kusano |
7d535a |
TRANSB - (input) char*
|
|
kusano |
7d535a |
On entry, TRANSB specifies the form of op( B ) to be used in
|
|
kusano |
7d535a |
the matrix multiplication as follows:
|
|
kusano |
7d535a |
TRANSB = 'N' or 'n', op( B ) = B.
|
|
kusano |
7d535a |
TRANSB = 'T' or 't', op( B ) = B'.
|
|
kusano |
7d535a |
TRANSB = 'C' or 'c', op( B ) = conjg( B' ).
|
|
kusano |
7d535a |
Unchanged on exit.
|
|
kusano |
7d535a |
M - (input) int
|
|
kusano |
7d535a |
On entry, M specifies the number of rows of the matrix
|
|
kusano |
7d535a |
op( A ) and of the matrix C. M must be at least zero.
|
|
kusano |
7d535a |
Unchanged on exit.
|
|
kusano |
7d535a |
N - (input) int
|
|
kusano |
7d535a |
On entry, N specifies the number of columns of the matrix
|
|
kusano |
7d535a |
op( B ) and the number of columns of the matrix C. N must be
|
|
kusano |
7d535a |
at least zero.
|
|
kusano |
7d535a |
Unchanged on exit.
|
|
kusano |
7d535a |
K - (input) int
|
|
kusano |
7d535a |
On entry, K specifies the number of columns of the matrix
|
|
kusano |
7d535a |
op( A ) and the number of rows of the matrix op( B ). K must
|
|
kusano |
7d535a |
be at least zero.
|
|
kusano |
7d535a |
Unchanged on exit.
|
|
kusano |
7d535a |
ALPHA - (input) double
|
|
kusano |
7d535a |
On entry, ALPHA specifies the scalar alpha.
|
|
kusano |
7d535a |
A - (input) SuperMatrix*
|
|
kusano |
7d535a |
Matrix A with a sparse format, of dimension (A->nrow, A->ncol).
|
|
kusano |
7d535a |
Currently, the type of A can be:
|
|
kusano |
7d535a |
Stype = NC or NCP; Dtype = SLU_D; Mtype = GE.
|
|
kusano |
7d535a |
In the future, more general A can be handled.
|
|
kusano |
7d535a |
B - DOUBLE PRECISION array of DIMENSION ( LDB, kb ), where kb is
|
|
kusano |
7d535a |
n when TRANSB = 'N' or 'n', and is k otherwise.
|
|
kusano |
7d535a |
Before entry with TRANSB = 'N' or 'n', the leading k by n
|
|
kusano |
7d535a |
part of the array B must contain the matrix B, otherwise
|
|
kusano |
7d535a |
the leading n by k part of the array B must contain the
|
|
kusano |
7d535a |
matrix B.
|
|
kusano |
7d535a |
Unchanged on exit.
|
|
kusano |
7d535a |
LDB - (input) int
|
|
kusano |
7d535a |
On entry, LDB specifies the first dimension of B as declared
|
|
kusano |
7d535a |
in the calling (sub) program. LDB must be at least max( 1, n ).
|
|
kusano |
7d535a |
Unchanged on exit.
|
|
kusano |
7d535a |
BETA - (input) double
|
|
kusano |
7d535a |
On entry, BETA specifies the scalar beta. When BETA is
|
|
kusano |
7d535a |
supplied as zero then C need not be set on input.
|
|
kusano |
7d535a |
C - DOUBLE PRECISION array of DIMENSION ( LDC, n ).
|
|
kusano |
7d535a |
Before entry, the leading m by n part of the array C must
|
|
kusano |
7d535a |
contain the matrix C, except when beta is zero, in which
|
|
kusano |
7d535a |
case C need not be set on entry.
|
|
kusano |
7d535a |
On exit, the array C is overwritten by the m by n matrix
|
|
kusano |
7d535a |
( alpha*op( A )*B + beta*C ).
|
|
kusano |
7d535a |
LDC - (input) int
|
|
kusano |
7d535a |
On entry, LDC specifies the first dimension of C as declared
|
|
kusano |
7d535a |
in the calling (sub)program. LDC must be at least max(1,m).
|
|
kusano |
7d535a |
Unchanged on exit.
