SLACPY(3)

SLACPY(3) 💅✨

okay so welcome to the Library Functions Manual page for /home/abui...RC/slacpy.f(3), bestie 🫶. This is the whole glow-up of SLACPY, and no cap: it copies all or part of a two-dimensional array/matrix from A to B. Let's get into it.

🌸 NAME 🌸

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/SRC/slacpy.f

That's the source file this manual page is about — periodt. 💖

✨ SYNOPSIS ✨

🌈 Functions/Subroutines 🌈

subroutine SLACPY (uplo, m, n, a, lda, b, ldb)

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

💅 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. (yes, same baddie energy, different section 😌)

🎯 Purpose 🎯

!>
!> SLACPY copies all or part of a two-dimensional matrix A to another
!> matrix B.
!>

🎀 Parameters 🎀

UPLO — the copy-scope selector, bestie. It's CHARACTER*1, and it says which part of matrix A gets copied to B: 'U' is the upper triangular part, 'L' is the lower triangular part, and anything otherwise means all of matrix A.

!>          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 — the row count. It's an INTEGER, and the rule is M >= 0.

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

N — the column count. It's an INTEGER, and the rule is N >= 0.

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

A — the source matrix, a REAL array with dimension (LDA,N). It's 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.

!>          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 — the leading dimension of array A. It's an INTEGER, and LDA >= max(1,M).

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

B — the destination matrix, a REAL array with dimension (LDB,N). On exit, B = A in the locations specified by UPLO.

!>          B is REAL array, dimension (LDB,N)
!>          On exit, B = A in the locations specified by UPLO.
!>

LDB — the leading dimension of array B. It's an INTEGER, and LDB >= max(1,M).

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