okay bestie, this is the Library Functions Manual page for /home/abui...N/clagge.f(3) — yes, the page name is doing the absolute most. 💅

💖 NAME 💖

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

✨ SYNOPSIS ✨

Functions/Subroutines

subroutine CLAGGE (m, n, kl, ku, d, a, lda, iseed, work, info)
    CLAGGE

🦋 Function/Subroutine Documentation 🦋

subroutine CLAGGE (integer m, integer n, integer kl, integer ku, real,
     dimension( * ) d, complex, dimension( lda, * ) a, integer lda, integer,
     dimension( 4 ) iseed, complex, dimension( * ) work, integer info)
     CLAGGE

🌸 Purpose 🌸

Bestie, CLAGGE 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.

🎀 Parameters 🎀

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

That’s the whole page, bestie! Footer energy: LAPACK Version 3.12.0, with the page path /home/abui...N/clagge.f(3) — the footer didn’t give us a date, so no fake timestamp energy here. 💜✨
