## Synopsis

### 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 (integer m, integer n, double precision, dimension( lda, * ) a, integer lda, complex*16, dimension( ldb, * ) b, integer ldb, complex*16, dimension( ldc, * ) c, integer ldc, 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)
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*16 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*16 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 DOUBLE PRECISION array, dimension (2*M*N)`
