Description
This routine is deprecated. Use Use mkl_sparse_?_mmfrom the
Intel® MKL
Inspector-executor Sparse BLAS interface instead.
The
mkl_?cscmm
routine performs a matrix-matrix operation defined as
C
:=
alpha
*
A
*
B
+
beta
*
C
or
C
:=
alpha
*
A
T
*
B
+
beta
*
C
,
or
C
:=
alpha
*
A
H
*
B
+
beta
*
C
,
where:
alpha
and
beta
are scalars,
B
and
C
are dense matrices,
A
is an
m
-by-
k
sparse matrix in compressed sparse column (CSC) format,
A
T
is the transpose of
A
, and
A
H
is the conjugate transpose of
A
.
This routine supports CSC format both with one-based indexing and zero-based indexing.
Input Parameters
Parameter descriptions are common for all implemented interfaces with the exception of data types that refer here to the FORTRAN 77 standard types. Data types specific to the different interfaces are described in the section
"Interfaces"
below.
transa
CHARACTER*1
.
Specifies the operation.
If
transa
=
'N'
or
'n'
, then
C
:=
alpha
*
A
*
B
+
beta
*
C
If
transa
=
'T'
or
't'
, then
C
:=
alpha
*
A
T
*
B
+
beta
*
C
,
If
transa
=
'C'
or
'c'
, then
C
:=
alpha
*
A
H
*
B
+
beta
*
