Matrix Operations

Matrix Calculator solves every matrix operation step by step — and lets you pick the method. From a quick determinant to a full singular value decomposition, you get the complete worked solution, not just the final answer. And it works fully offline.

Whether you're a student checking homework or just need fast, reliable computations, this calculator shows the full process for over 25 matrix operations, often with several algorithms to choose from. Results are shown as exact fractions or decimals, and you can save and edit any solution to revisit later.
