    DERRED

🍓 Purpose 🍓

Bestie, the purpose is literally this: DERRED tests the error exits for the eigenvalue driver routines for DOUBLE PRECISION matrices. The exact PATH/driver/description lineup is giving iconic ✨

• SEV with DGEEV — find eigenvalues/eigenvectors for nonsymmetric A
• SES with DGEES — find eigenvalues/Schur form for nonsymmetric A
• SVX with DGEEVX — SGEEV + balancing and condition estimation
• SSX with DGEESX — SGEES + balancing and condition estimation
• DBD with DGESVD — compute SVD of an M-by-N matrix A
  • DGESDD — compute SVD of an M-by-N matrix A (by divide and conquer)
  • DGEJSV — compute SVD of an M-by-N matrix A where M >= N
  • DGESVDX — compute SVD of an M-by-N matrix A(by bisection and inverse iteration)
  • DGESVDQ — compute SVD of an M-by-N matrix A(with a QR-Preconditioned )

💜 Parameters 💜

• PATH — is CHARACTER*3; the LAPACK path name for the routines to be tested 🦋
• NUNIT — is INTEGER; the unit number for output 🌸

mwah 💋 source/version tea at the very end: LAPACK, Version 3.12.0, page TESTING/EIG/derred.f(3). The footer doesn't give a date, so I'm not inventing one, bestie 🎀💖
