# Function/Subroutine Documentation

## subroutine zlacpy (characterUPLO, integerM, integerN, complex*16, dimension( lda, * )A, integerLDA, complex*16, dimension( ldb, * )B, integerLDB)

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).
```
