Free matrix calculator with step-by-step solutions — addition, multiplication, determinants, inverses, and eigenvalues.
ML3X is a free visual matrix calculator that shows step-by-step solutions for every operation. Add, subtract, and multiply matrices up to 5x5, compute determinants, find inverses, and calculate eigenvalues — all with detailed intermediate calculations displayed on screen. Built for linear algebra students, engineers, and data scientists who want their work shown, not just the final answer.
