TESTING/MATGEN/slarge.f(3)

💅 NAME 💅

okay so this page is TESTING/MATGEN/slarge.f — and folded in near the top, the manual energy is TESTING/MATGEN/slarge.f(3) from the Library Functions Manual. It’s giving LAPACK test-matrix realness, bestie. ✨

✨ SYNOPSIS ✨

Functions/Subroutines

• subroutine slarge (n, a, lda, iseed, work, info) — SLARGE

---

💖 Function/Subroutine Documentation 💖

   subroutine slarge (integer n, real, dimension( lda, * ) a, integer lda,
       integer, dimension( 4 ) iseed, real, dimension( * ) work, integer info)

SLARGE

🎀 Purpose: 🎀

SLARGE pre- and post-multiplies a real general n by n matrix A with a random orthogonal matrix: A = U*D*U'.

🌸 Parameters 🌸

• N — N is INTEGER. The order of the matrix A. N >= 0.
• A — A is REAL array, dimension (LDA,N). On entry, the original n by n matrix A. On exit, A is overwritten by U*A*U' for some random orthogonal matrix U.
• LDA — LDA is INTEGER. The leading dimension of the array A. LDA >= N.
• ISEED — ISEED is INTEGER array, dimension (4). On entry, the seed of the random number generator; the array elements must be between 0 and 4095, and ISEED(4) must be odd. On exit, the seed is updated.
• WORK — WORK is REAL array, dimension (2*N).
• INFO — INFO is INTEGER
  • = 0: successful exit
  • < 0: if INFO = -i, the i-th argument had an illegal value

🌈 footer vibes, bestie: LAPACK Version 3.12.0, page TESTING/MATGEN/slarge.f(3). The footer didn’t hand me a separate date, so I’m not making one up — no cap. 💅💖
