How It Works
Set the dimensions for matrices A and B, enter values, and select an operation. The calculator validates dimensions and performs the operation, displaying the result in a clean matrix grid.
Supported Operations
- Addition & Subtraction · Requires matrices of same dimensions
- Multiplication · Columns of A must equal rows of B
- Transpose · Flips rows and columns (A^T, B^T)
- Determinant · Square matrices only (det(A), det(B))
- Inverse · Square matrices with non-zero determinant (A^−1, B^−1)
Frequently Asked Questions
What matrix dimensions are supported?
Matrices up to 6×6 dimensions are supported. Select the number of rows and columns for each matrix before entering values.
When can I calculate an inverse?
A matrix inverse only exists for square matrices (same number of rows and columns) with a non-zero determinant. Singular matrices (determinant = 0) have no inverse.
