Matrix Calculator
Enter matrices in the grid editor (or as [[1,2],[3,4]]). Determinants show cofactor expansion, inverses show Gauss–Jordan elimination, and every result is verified (for example A·A⁻¹ = I).
How to use the matrix calculator
- Choose an operation.
- Set the size and fill in the entries.
- Review each row operation.
