ZLACPY copies all or part of one two-dimensional array to another.

## Function/Subroutine Documentation

### subroutine zlacpy (character uplo, integer m, integer n, complex*16, dimension( lda, * ) a, integer lda, complex*16, dimension( ldb, * ) b, integer ldb)

ZLACPY copies all or part of one two-dimensional array to another.

Purpose:

``` ZLACPY copies all or part of a two-dimensional matrix A to another
matrix B.```
Parameters

UPLO

```          UPLO is CHARACTER*1
Specifies the part of the matrix A to be copied to B.
= 'U':      Upper triangular part
= 'L':      Lower triangular part
Otherwise:  All of the matrix A```

M

```          M is INTEGER
The number of rows of the matrix A.  M >= 0.```

N

```          N is INTEGER
The number of columns of the matrix A.  N >= 0.```

A

```          A is COMPLEX*16 array, dimension (LDA,N)
The m by n matrix A.  If UPLO = 'U', only the upper trapezium
is accessed; if UPLO = 'L', only the lower trapezium is
accessed.```

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 exit, B = A in the locations specified by UPLO.```

LDB

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