Performs a very simple matrix-matrix multiplication
Usage
- SUBROUTINE CLACRM(
-
M, N, A, LDA, B, LDB, C, LDC, RWORK )
- INTEGER
-
LDA, LDB, LDC, M, N
- REAL
-
B( LDB, * ), RWORK( * )
- COMPLEX
-
A( LDA, * ), C( LDC, * )
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.
Arguments
- M (input) INTEGER
-
The number of rows of the matrix A and of the matrix C. M >= 0.
- N (input) INTEGER
-
The number of columns and rows of the matrix B and the number of columns of the matrix C. N >= 0.
- A (input) COMPLEX array, dimension (LDA, N)
-
A contains the M by N matrix A.
- LDA (input) INTEGER
-
The leading dimension of the array A. LDA >=max(1,M).
- B (input) REAL array, dimension (LDB, N)
-
B contains the N by N matrix B.
- LDB (input) INTEGER
-
The leading dimension of the array B. LDB >=max(1,N).
- C (input) COMPLEX array, dimension (LDC, N)
-
C contains the M by N matrix C.
- LDC (input) INTEGER
-
The leading dimension of the array C. LDC >=max(1,N).
- RWORK (workspace) REAL array, dimension (2*M*N)
