Matrix Calculator

MatrixCalculator.net is a free online matrix calculator that supports 32 matrix operations, including matrix multiplication, inverse, determinant, RREF, rank, powers, matrix decompositions, and more. It provides detailed step-by-step solutions for major matrix calculations, supports fraction and decimal input, and is available in both English and Spanish.
MatrixCalculator.net also features its own Matrix Multiplication Tutor, an interactive learning tool built around “learning by doing.” It is designed for people who are learning matrix multiplication, want to understand the calculation rules, or need practice working through the process themselves. With visual row-and-column cues and step-by-step guidance, users complete each part of the calculation instead of simply being shown the answer. The goal is to help users truly understand the Row × Column rule and gradually become confident enough to complete matrix multiplication independently.
