About This Tool
The Matrix Calculator performs common matrix operations on 2×2 and 3×3 matrices: addition, multiplication, and determinant calculation. Enter the elements of one or two matrices and select an operation to see the result.
Matrices are fundamental to linear algebra and appear in computer graphics, machine learning, physics, engineering, and data science. Operations like multiplication and determinant finding are core skills in many technical fields.
Choose the matrix size, enter values into the grid inputs, select an operation, and get an instant result displayed in a clear matrix format.
