About this calculator
The Matrix Calculator performs addition, subtraction, multiplication, determinant, inverse, and transpose on 2×2 and 3×3 matrices. Enter your matrix values and choose an operation to get the result instantly. Useful for linear algebra, computer graphics, systems of equations, and engineering coursework.
Common examples
- [[1,2],[3,4]] + [[5,6],[7,8]] = [[6,8],[10,12]]
- det([[2,1],[4,3]]) = 2×3 − 1×4 = 2
- [[1,2],[3,4]] × [[2,0],[1,3]] = [[4,6],[10,12]]
- Inverse of [[2,1],[5,3]] = [[3,−1],[−5,2]] (det = 1)
- Transpose of [[1,2,3],[4,5,6],[7,8,9]] = [[1,4,7],[2,5,8],[3,6,9]]
