zlacrm (m, n, a, lda, b, ldb, c, ldc, rwork)
ZLACRM multiplies a complex matrix by a square real matrix.
Detailed Description¶
Function Documentation¶
subroutine clacrm (integer m, integer n, complex, dimension( lda, * ) a, integer lda, real, dimension( ldb, * ) b, integer ldb, complex, dimension( ldc, * ) c, integer ldc, real, dimension( * ) rwork)¶
CLACRM multiplies a complex matrix by a square real matrix.
Purpose:
CLACRM performs a very simple matrix-matrix multiplication:
C := A * B,
where A is M by N and complex; B is N by N and real;
C is M by N and complex.
Parameters
M
M is INTEGER
The number of rows of the matrix A and of the matrix C.
M >= 0.
N
N is INTEGER
The number of columns and rows of the matrix B and
the number of columns of the matrix C.
N >= 0.
A
A is COMPLEX array, dimension (LDA, N)
On entry, A contains the M by N matrix A.
LDA
LDA is INTEGER
The leading dimension of the array A. LDA >=max(1,M).
B
B is REAL array, dimension (LDB, N)
On entry, B contains the N by N matrix B.
LDB
LDB is INTEGER
The leading dimension of the array B. LDB >=max(1,N).
C
C is COMPLEX array, dimension (LDC, N)
On exit, C contains the M by N matrix C.
LDC
LDC is INTEGER
The leading dimension of the array C. LDC >=max(1,N).
RWORK
RWORK is REAL array, dimension (2*M*N)
