About the Matrix Calculator
The Matrix Calculator performs linear-algebra operations on matrices you type row-by-row (numbers separated by spaces/commas). It supports addition, subtraction, multiplication, transpose, and determinant. Dimension validation is automatic (e.g. multiply needs A columns = B rows).
Useful for graphics, machine learning, physics, and math homework. All computed in the browser.
FAQ
Is this Matrix Calculator accurate?
Yes. It uses standard formulas and runs directly in your browser at full JavaScript precision (plus BigInt/decimal.js for large numbers where needed).
Is my data sent to a server?
No. All calculations happen entirely on your device. No values are sent to or stored on our servers.
