📦 version 3.12.0, in opensuse-leap 16.0

🌸 NAME 🌸

okay so the name is literally:

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/MATGEN/zlagge.f

This is the Library Functions Manual page for /home/abui...N/zlagge.f(3), bestie. 💅

✨ SYNOPSIS ✨

🦋 Functions/Subroutines 🦋

  • subroutine ZLAGGE (m, n, kl, ku, d, a, lda, iseed, work, info) — ZLAGGE

🧚 Function/Subroutine Documentation 🧚

subroutine ZLAGGE (integer m, integer n, integer kl, integer ku, double
       precision, dimension( * ) d, complex*16, dimension( lda, * ) a, integer
       lda, integer, dimension( 4 ) iseed, complex*16, dimension( * ) work,
       integer info)

ZLAGGE

💫 Purpose 💫

okay so ZLAGGE generates a complex general m by n matrix A, by pre- and post-multiplying a real diagonal matrix D with random unitary matrices:

A = U*D*V

The lower and upper bandwidths may then be reduced to kl and ku by additional unitary transformations. slay. ✨

🌸 Parameters 🌸

  • 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.
  • KL — KL is INTEGER; the number of nonzero subdiagonals within the band of A. 0 <= KL <= M-1.
  • KU — KU is INTEGER; the number of nonzero superdiagonals within the band of A. 0 <= KU <= N-1.
  • D — D is DOUBLE PRECISION array, dimension (min(M,N)); the diagonal elements of the diagonal matrix D.
  • A — A is COMPLEX*16 array, dimension (LDA,N); the generated m by n matrix A.
  • LDA — LDA is INTEGER; the leading dimension of the array A. LDA >= M.
  • 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 COMPLEX*16 array, dimension (M+N).
  • INFO — INFO is INTEGER; = 0: successful exit; < 0: if INFO = -i, the i-th argument had an illegal value.
