Description
This routine is deprecated. Use mkl_sparse_?_trsm from the
Intel® MKL
Inspector-executor Sparse BLAS interface instead.
The
mkl_?bsrsm
routine solves a system of linear equations with matrix-matrix operations for a sparse matrix in the BSR 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 a BSR 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 the matrix-matrix product is computed as
C
:=
alpha
*inv(
A
)*
B.
If
transa
=
'T'
or
't'
or
'C'
or
'c'
, then the matrix-vector product is computed as
C
:=
alpha
*inv(
A
T
)*
B
.
m
INTEGER
.
Number of block columns of the matrix
A
.
n
INTEGER
.
Number of columns of the matrix
C
.
lb
INTEGER
.
Size of the block in the matrix
A
.
alpha
REAL

mkl_sbsrsm
