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

## Function/Subroutine 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:
 [in] M ``` M is INTEGER The number of rows of the matrix A and of the matrix C. M >= 0.``` [in] 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.``` [in] A ``` A is REAL array, dimension (LDA, M) A contains the M by M matrix A.``` [in] LDA ``` LDA is INTEGER The leading dimension of the array A. LDA >=max(1,M).``` [in] B ``` B is REAL array, dimension (LDB, N) B contains the M by N matrix B.``` [in] LDB ``` LDB is INTEGER The leading dimension of the array B. LDB >=max(1,M).``` [in] C ``` C is COMPLEX array, dimension (LDC, N) C contains the M by N matrix C.``` [in] LDC ``` LDC is INTEGER The leading dimension of the array C. LDC >=max(1,M).``` [out] RWORK ` RWORK is REAL array, dimension (2*M*N)`
