lis_solve_kernel(3f)

✨ NAME ✨

lis_solve_kernel — okay bestie, this one solves the linear equation with the predefined preconditioner 💅

This page comes from the Lis Library Functions manual, and it's literally all about lis_solve_kernel(3f) 🎀

🌸 SYNOPSIS 🌸

subroutine lis_solve_kernel(LIS_SOLVER solver, LIS_INTEGER ierr);

🦋 DESCRIPTION 🦋

So real talk: this subroutine solves the linear equation with the specified solver and the predefined preconditioner. That's the whole assignment, and it ate. ✨

💖 INPUT 💖

• A — the coefficient matrix 🧚
• b — the right hand side vector
• x — the initial vector
• solver — the solver 👑
• precon — the preconditioner

👑 OUTPUT 👑

• x — the solution 🌟
• solver — the number of iterations, the execution time, etc. 💀

💀 NOTE 💀

See lis-($VERSION)/src/esolver/lis esolver ii.c, which computes the smallest eigenvalue by calling lis_solve_kernel multiple times, for example.

No cap, that's the example they're giving you. 🫶
