ZGET35(3)

💅 NAME

okay so this is the zget35.f(3) page, and yes bestie, it lives in the Library Functions Manual. The NAME is literally this whole path:

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/EIG/zget35.f

subroutine ZGET35 (rmax, lmax, ninfo, knt, nin)
    ZGET35

🎀 Function/Subroutine Documentation

💖 subroutine ZGET35

subroutine ZGET35 (double precision rmax, integer lmax, integer ninfo,
       integer knt, integer nin)
       ZGET35

🌸 Purpose:

okay so here's the tea: ZGET35 tests ZTRSYL, a routine for solving the Sylvester matrix equation

op(A)*X + ISGN*X*op(B) = scale*C,

A and B are assumed to be in Schur canonical form, op() represents an optional transpose, and ISGN can be -1 or +1. Scale is an output less than or equal to 1, chosen to avoid overflow in X.

The test code verifies that the following residual is order 1:

norm(op(A)*X + ISGN*X*op(B) - scale*C) /
    (EPS*max(norm(A),norm(B))*norm(X))

🍓 Parameters

• RMAX — RMAX is DOUBLE PRECISION; it's the value of the largest test ratio. 💅
• LMAX — LMAX is INTEGER; it's the example number where the largest test ratio was achieved.
• NINFO — NINFO is INTEGER; it's the number of examples where INFO is nonzero.
• KNT — KNT is INTEGER; it's the total number of examples tested.
• NIN — NIN is INTEGER; it's the input logical unit number.
