## 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)`
