?lacpy
Copies all or part of one two-dimensional array to another.
Syntax
call slacpy( uplo, m, n, a, lda, b, ldb )
call dlacpy( uplo, m, n, a, lda, b, ldb )
call clacpy( uplo, m, n, a, lda, b, ldb )
call zlacpy( uplo, m, n, a, lda, b, ldb )

Description
The routine copies all or part of a two-dimensional matrix A to another matrix B.
Input Parameters
The data types are given for the Fortran interface.
- uplo
-
CHARACTER*1.
Specifies the part of the matrix A to be copied to B.
If uplo = 'U', the upper triangular part of A;
if uplo = 'L', the lower triangular part of A.
Otherwise, all of the matrix A is copied.
- m
-
INTEGER. The number of rows in the matrix A (m≥ 0).
- n
-
INTEGER. The number of columns in A (n≥ 0).
- a
-
REAL for slacpy
DOUBLE PRECISION for dlacpy
COMPLEX for clacpy
DOUBLE COMPLEX for zlacpy.
Array a(lda,*), contains the m-by-n matrix A.
The second dimension of a must be at least max(1,n).
If uplo = 'U', only the upper triangle or trapezoid is accessed; if uplo = 'L', only the lower triangle or trapezoid is accessed.
- lda
- INTEGER. The leading dimension of a; lda≥max(1,m).
- ldb
-
INTEGER. The leading dimension of the output array b; ldb≥ max(1, m).
Output Parameters
- b
-
REAL for slacpy
DOUBLE PRECISION for dlacpy
COMPLEX for clacpy
DOUBLE COMPLEX for zlacpy.
Array b(ldb,*), contains the m-by-n matrix B.
The second dimension of b must be at least max(1,n).
On exit, B = A in the locations specified by uplo.
