Usage

Functions

subroutine clarcm (m, n, a, lda, b, ldb, c, ldc, rwork)
CLARCM copies all or part of a real two-dimensional array to a complex array. subroutine zlarcm (m, n, a, lda, b, ldb, c, ldc, rwork)

Detailed Description

Function Documentation

subroutine clarcm (integer m, integer n, real, dimension( lda, * ) a, integer lda, complex, dimension( ldb, * ) b, integer ldb, complex, dimension( ldc, * ) c, integer ldc, real, dimension( * ) rwork)

CLARCM copies all or part of a real two-dimensional array to a complex array.

Purpose:

!>
!> CLARCM performs a very simple matrix-matrix multiplication:
!>          C := A * B,
!> where A is M by M and real; B is M by N and complex;
!> 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 REAL array, dimension (LDA, M)
!>          On entry, A contains the M by M matrix A.
!>

LDA

!>          LDA is INTEGER
!>          The leading dimension of the array A. LDA >=max(1,M).
!>

B

!>          B is COMPLEX array, dimension (LDB, N)
!>          On entry, B contains the M by N matrix B.
!>

LDB

!>          LDB is INTEGER
!>          The leading dimension of the array B. LDB >=max(1,M).
!>

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,M).
!>

RWORK

!>          RWORK is REAL array, dimension (2*M*N)
!>
