A matrix calculator is a tool for performing linear algebra operations on matrices. Our free online matrix calculator works with 3x3 matrices and computes the determinant, trace, and invertibility. Matrix operations are fundamental in engineering, physics, computer graphics, machine learning, and economics. Whether you are solving systems of linear equations or transforming coordinates, our tool provides fast and accurate results.
Enter your 3x3 matrix values into the nine input fields in the MATRIX tab. Press ENTER or click the execute button, and the calculator will display the determinant, trace, and whether the matrix is invertible. A singular matrix (determinant zero) is clearly flagged. You can modify any value and re-run the operation instantly.
Matrix calculations by hand are tedious and error-prone. Our tool performs the operations instantly with no signup and no software installation. It is ideal for students verifying homework, engineers solving linear systems, and anyone working with transformations. The calculator handles the arithmetic so you can focus on interpreting the results.
Currently the calculator supports 3x3 matrices. Support for other sizes is planned.
It computes the determinant, trace, and checks if the matrix is invertible.
The determinant is a scalar value that indicates whether a matrix is invertible. A determinant of zero means the matrix is singular.
Yes. The matrix accepts integer and decimal values.
Yes, completely free with no signup required.
