Description
This routine is deprecated. Use mkl_sparse_?_trsm from the
Intel® MKL
Inspector-executor Sparse BLAS interface instead.
The
mkl_?skysm
routine solves a system of linear equations with matrix-matrix operations for a sparse matrix in the skyline storage format:
C
:=
alpha
*inv(
A
)*
B
or
C
:=
alpha
*inv(
A
T
)*
B
,
where:
alpha
is scalar,
B
and
C
are dense matrices,
A
is a sparse upper or lower triangular matrix with unit or non-unit main diagonal,
A
T
is the transpose of
A
.
This routine supports only one-based indexing of the input arrays.
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 system of linear equations.
If
transa
=
'N'
or
'n'
, then
C
:=
alpha
*inv(
A
)*
B
,
If
transa
=
'T'
or
't'
or
'C'
or
'c'
, then
C
:=
alpha
*inv(
A
T
)*
B
,
m
INTEGER
.
Number of rows of the matrix
A
.
n
INTEGER
.
