SGET35(3)

💖 NAME 💖

Okay bestie, welcome to the Library Functions Manual — this page is SGET35(3), and the header stamp path is /home/abui...IG/sget35.f(3). The name line is literally this path, no cap:

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/EIG/sget35.f

Let’s get into it, periodt.

✨ SYNOPSIS ✨

🌈 Functions/Subroutines 🌈

• subroutine SGET35 (rmax, lmax, ninfo, knt) — SGET35

---

🦋 Function/Subroutine Documentation 🦋

subroutine SGET35 (real rmax, integer lmax, integer ninfo, integer knt)

SGET35

🍓 Purpose 🍓

Okay so SGET35 tests STRSYL, 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))

This is the main character energy of the page, iykyk.

🎀 Parameters 🎀

• RMAX — RMAX is REAL; this is the value of the largest test ratio.
• LMAX — LMAX is INTEGER; this is the example number where the largest test ratio was achieved.
• NINFO — NINFO is INTEGER; this is the number of examples where INFO is nonzero.
• KNT — KNT is INTEGER; this is the total number of examples tested.

Sign-off time, bestie: footer source/version/date stamp: LAPACK Version 3.12.0 and /home/abui...IG/sget35.f(3). That’s the whole page. Slay 💅✨🦋
