💖 NAME 💖

gelyap — Standard Lyapunov and Stein Equations, bestie!!

So like, this whole page is about the solvers for standard Lyapunov and Stein equations with general coefficient matrices. That's the vibe. That's the whole gig. 🦋

✨ SYNOPSIS ✨

🎀 Topics 🎀

Ok so there's three little sub-areas here, and each one is its own thing:

• Single Precision — single precision solvers for standard Lyapunov and Stein equations with general coefficient matrices. Yes queen, less bits, more speed. 💅
• Double Precision — double precision solvers for standard Lyapunov and Stein equations with general coefficient matrices. For when you want the precision, periodt. ✨
• C-Interface — the C-Interface for generalized Lyapunov and Stein equations with triangular coefficient matrices. (Note it says generalized and triangular here — that's literally what it says, don't come for me. 👀)

🌸 DETAILED DESCRIPTION 🌸

Solvers for standard Lyapunov and Stein equations with general coefficient matrices. That's the headline, no cap.

This section contains the solver for standard Lyapunov and Stein equations with general coefficient matrices. 🫶

And here's the lil detail that matters: the required Schur decomposition for the internal triangular solver is computed with LAPACK if it is required. Like, only if it's actually needed. LAPACK is the plug, iykyk. 🔥

Not me getting emotional over a machine-generated author field 😭 it literally wrote itself. Iconic behaviour tbh.

Okay bestie, that's the whole page — we ate and left no crumbs. 💖
