About Matrix Calculator

A matrix calculator performs arithmetic and algebraic operations on matrices — rectangular arrays of numbers. Matrices are fundamental in linear algebra, 3D graphics, machine learning, economics, and physics. This tool supports addition, subtraction, multiplication, determinant, inverse, and transpose for 2×2 and 3×3 matrices — all running privately in your browser.

Frequently Asked Questions

A matrix has no inverse when its determinant is zero. Such a matrix is called singular. You cannot divide by zero in matrix arithmetic, so the inverse is undefined.

No. In general, A × B ≠ B × A. Matrix multiplication is associative and distributive but not commutative, unlike regular number multiplication.
