How to use
- Pick the sizes of matrices A and B and fill in the cells. Fractions (1/3) and roots (√2) are fine.
- Press an operation to see the result below. You can copy the result into A or B to keep going.
- If there is no inverse (determinant 0), it says so.
- The Vector tab handles 2D and 3D vectors: dot product, cross product (3D), magnitude and angle. The angle unit follows the calculator setting.
