Matrix Calculator
What is a Matrix Calculator?
Perform 2x2, 3x3, and NxN matrix operations: Matrix Addition, Subtraction, Matrix Multiplication ($A \times B$), Transpose ($A^T$), Determinant ($det(A)$), and Matrix Inverse ($A^{-1}$).
Why Use This Tool?
- Linear Algebra Homework: Verify matrix operations, determinants, and inverses for linear algebra.
- 3D Graphics & Game Dev: Compute 3D transformation matrices and vector dot products.
- Machine Learning & Data Science: Inspect matrix multiplication dimensions and linear systems.
How to Use
- Select Matrix Dimensions (2x2, 3x3, 4x4 or Custom NxM).
- Enter numerical values into Matrix A and Matrix B grids.
- Select Operation (+, -, *, Determinant, Inverse, Transpose) to view result grid.
Real Working Example
Input:
Matrix A (2x2): [[1, 2], [3, 4]] | Operation: Determinant det(A)
Output Result:
det(A) = (1*4) - (2*3) = -2 | Inverse A⁻¹: [[-2, 1], [1.5, -0.5]]

Frequently Asked Questions
When is matrix multiplication valid?
Matrix multiplication A * B is valid only when the number of columns in Matrix A equals the number of rows in Matrix B.
What does a matrix determinant det(A) = 0 mean?
If det(A) = 0, the matrix is singular and does not have a matrix inverse.
Is it free?
Yes, 100% free.
Does it support 3x3 and 4x4 matrices?
Yes, 2x2, 3x3, 4x4, and custom NxM matrices are supported.
Is my matrix data stored anywhere?
No, all matrix computations run 100% locally in your browser memory.
