Numerical Linear Algebra, Where the Algebra Stops Being the Arithmetic
A collection of illustrated essays and figures about floating-point arithmetic, numerical stability, error, and the behavior of linear-algebra algorithms.
Why it surfacedThis site makes an abstract subject tangible: a thirteen-by-thirteen Hilbert solve can return 0.05 where 8 belongs, while still achieving a backward error of 10⁻¹⁷. Its 19 essays and measured figures repeatedly separate an algorithm’s fault from a problem’s conditioning, giving numerical linear algebra unusually clear explanations and memorable examples.
