Solve matrix problems online and see results as decimals or fractions.
What is the Matrix Calculator?
Solve matrix problems for school, university and engineering. Choose a size from 2×2 to 5×5 and calculate A + B, A − B, A × B, A², the transpose, the determinant or the inverse. You can type decimals or fractions like 1/2, and results are shown as neat fractions whenever possible.
How to use the Matrix Calculator
- Choose the matrix size and the operation.
- Type the values of A (and B).
- Read the result below.
Quick facts
- Matrix multiplication is not commutative: A × B is usually different from B × A.
- A matrix has an inverse only if its determinant is not zero.
- det(A) for a 2×2 matrix [[a,b],[c,d]] = ad − bc.
Frequently asked questions
Can I enter fractions?
Yes, e.g. 3/4 or -1/2.
Why does it say singular?
The determinant is 0, so no inverse exists.
Can I multiply different sizes?
This calculator uses square matrices of the same size.
Is it free?
Yes.
This matrix calculator is 100% free, needs no signup and works on phones, tablets and computers. Your data is processed in your browser and never uploaded.
