## 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:***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)
