## Function/Subroutine Documentation

### subroutine slacpy (character UPLO, integer M, integer N, real, dimension( lda, * ) A, integer LDA, real, dimension( ldb, * ) B, integer LDB)

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

**Purpose:**

SLACPY 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 REAL array, dimension (LDA,N) The m by n matrix A. If UPLO = 'U', only the upper triangle or trapezoid is accessed; if UPLO = 'L', only the lower triangle or trapezoid is accessed.

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

*B*B is REAL 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).
