Matrix Calculator - Perform Matrix Operations Online
Matrix operations are fundamental in linear algebra, computer graphics, machine learning, and engineering. Our free online matrix calculator supports all essential operations for 2x2 and 3x3 matrices, making it easy to perform calculations that would otherwise require tedious manual work or specialized software.
The calculator supports matrix addition, subtraction, and multiplication, as well as transpose and determinant calculations. You can also perform scalar multiplication to scale all elements of a matrix by a constant value. Each operation follows standard mathematical definitions to ensure accurate results.
Matrix multiplication is perhaps the most commonly needed operation. Unlike regular multiplication, matrix multiplication is not commutative, meaning A times B does not equal B times A in general. Our tool lets you compute both directions and compare results instantly. The determinant function helps you determine whether a matrix is invertible.
Simply select your matrix size, enter values into the grid inputs, choose an operation, and click calculate. The result appears immediately in a clean grid format that you can copy to your clipboard. All computation happens locally in your browser with no data sent to external servers.
