🎀 NAME 🎀

This is the TESTING/EIG/cerred.f page, bestie — yes, from the LAPACK Library Functions Manual — and the name on the tin is exactly TESTING/EIG/cerred.f. Periodt. 💅

✨ SYNOPSIS ✨

🌸 Functions/Subroutines 🌸

subroutine cerred (path, nunit)
    CERRED

🦋 Function/Subroutine Documentation 🦋

subroutine cerred (character*3 path, integer nunit)
    CERRED

🔥 Purpose 🔥

CERRED tests the error exits for the eigenvalue driver routines for REAL matrices:

PATH  driver   description
----  ------   -----------
CEV   CGEEV    find eigenvalues/eigenvectors for nonsymmetric A
CES   CGEES    find eigenvalues/Schur form for nonsymmetric A
CVX   CGEEVX   CGEEV + balancing and condition estimation
CSX   CGEESX   CGEES + balancing and condition estimation
CBD   CGESVD   compute SVD of an M-by-N matrix A
      CGESDD   compute SVD of an M-by-N matrix A(by divide and
               conquer)
      CGEJSV   compute SVD of an M-by-N matrix A where M >= N
      CGESVDX  compute SVD of an M-by-N matrix A(by bisection
               and inverse iteration)
      CGESVDQ  compute SVD of an M-by-N matrix A(with a
               QR-Preconditioned )

🫶 Parameters 🫶

  • PATH — PATH is CHARACTER*3; it’s the LAPACK path name for the routines to be tested. 💖
  • NUNIT — NUNIT is INTEGER; it’s the unit number for output. ✨
