larcm - larcm: real * complex matrix-matrix multiply


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

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)
