Numerical Stability

Numerical stability measures how much rounding and tiny input changes can distort an algorithm’s output on real computers using floating-point arithmetic.

Systems of Linear Equations

A system of linear equations asks for numbers that make several linear relationships true at the same time, which we compactly write as Ax = b.

Gaussian Elimination

Gaussian elimination is a systematic way to solve linear equations by cleaning a matrix into an upper-triangular form using row swaps, scaling, and adding multiples of rows.

Determinant

The determinant of a square matrix measures how a linear transformation scales volume and whether it flips orientation.

Matrix Inverse

A matrix inverse undoes the effect of a linear transformation, just like dividing by a number undoes multiplication.
