What is Matrix?

Matrix operations are fundamental in linear algebra, computer graphics, and data science. This calculator supports 2x2 and 3x3 matrices.

How it works

We implement standard matrix algorithms: element-wise add/subtract, row x column multiplication, Laplace expansion for determinants.
