## Function/Subroutine Documentation

### subroutine clacrm (integerM, integerN, complex, dimension( lda, * )A, integerLDA, real, dimension( ldb, * )B, integerLDB, complex, dimension( ldc, * )C, integerLDC, real, dimension( * )RWORK)

CLACRM multiplies a complex matrix by a square real matrix.

Purpose:

``` CLACRM performs a very simple matrix-matrix multiplication:
C := A * B,
where A is M by N and complex; B is N by N and real;
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 COMPLEX array, dimension (LDA, N)
A contains the M by N matrix A.
```

LDA

```          LDA is INTEGER
The leading dimension of the array A. LDA >=max(1,M).
```

B

```          B is REAL array, dimension (LDB, N)
B contains the N by N matrix B.
```

LDB

```          LDB is INTEGER
The leading dimension of the array B. LDB >=max(1,N).
```

C

```          C is COMPLEX 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,N).
```

RWORK

```          RWORK is REAL array, dimension (2*M*N)
```
