Functions/Subroutines


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.

Function/Subroutine Documentation

subroutine zlarcm (integerM, integerN, double precision, dimension( lda, * )A, integerLDA, complex*16, dimension( ldb, * )B, integerLDB, complex*16, dimension( ldc, * )C, integerLDC, double precision, dimension( * )RWORK)

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

Purpose: 



 ZLARCM 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 DOUBLE PRECISION array, dimension (LDA, M)


          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 DOUBLE PRECISION array, dimension (LDB, N)


          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*16 array, dimension (LDC, N)


          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 DOUBLE PRECISION array, dimension (2*M*N)
