Matrix Calculator

For A(m×n) × B(n×p), each element is the dot product of a row from A and a column from B. The result is an m×p matrix. Columns in A must equal rows in B.

The determinant is a scalar value from a square matrix. It indicates invertibility (non-zero determinant) and represents the scaling factor of the linear transformation.

A square matrix is invertible if and only if its determinant is non-zero. The inverse satisfies A × A⁻¹ = I (identity matrix).
