subroutine dlacpy (character uplo, integer m, integer n, double precision,
    dimension( lda, * ) a, integer lda, double precision, dimension( ldb, *
    ) b, integer ldb)

DLACPY copies all or part of one two-dimensional array to another. same energy, different section, bestie. πŸ’–

πŸŽ€ Purpose πŸŽ€

okay so the actual purpose: DLACPY copies all or part of a two-dimensional matrix A to another matrix B. That's it. That's the whole vibe. ✨

πŸ’– Parameters πŸ’–

  • UPLO β€” UPLO is CHARACTER*1. This tells us which part of matrix A gets copied into B. 'U': upper triangular part. 'L': lower triangular part. Otherwise: all of the matrix A. no cap, β€œotherwise” means the whole thing. πŸ‘‘
  • M β€” M is INTEGER. The number of rows of the matrix A. It must be M >= 0. fr fr.
  • N β€” N is INTEGER. The number of columns of the matrix A. It must be N >= 0. 🫢
  • A β€” A is DOUBLE PRECISION array, dimension (LDA,N). This is 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. the way that matters, okay? πŸ’€
  • LDA β€” LDA is INTEGER. The leading dimension of the array A. It must be LDA >= max(1,M). slay. ✨
  • B β€” B is DOUBLE PRECISION array, dimension (LDB,N). On exit, B = A in the locations specified by UPLO. that's the whole copy situation. πŸ’–
  • LDB β€” LDB is INTEGER. The leading dimension of the array B. It must be LDB >= max(1,M). iconic. πŸ’…

okay bestie, cute sign-off time: this footer says LAPACK, Version 3.12.0, and page SRC/dlacpy.f(3) β€” and there’s no separate date in the footer, so I’m not gonna invent one. πŸ’œπŸ¦‹
