What matrix sizes are supported?

Each matrix can be from 1×1 up to 5×5. For multiplication, the number of columns in matrix A must equal the number of rows in matrix B.

Why is the inverse operation limited to 2×2 and 3×3?

Computing the inverse of larger matrices is numerically complex in the browser. For larger matrices, use a dedicated tool like NumPy or MATLAB.

What does it mean if the determinant is zero?

A determinant of zero means the matrix is singular and has no inverse.

关于此工具

Enter up to two matrices using on-screen grid inputs (up to 5×5 each). Choose an operation: Add, Subtract, Multiply, Transpose, Determinant (square matrices), or Inverse (2×2 and 3×3). Results are displayed instantly, and matrix multiplication includes a step-by-step dot-product breakdown so you can follow the working.

使用方法

1 Set the row and column dimensions for Matrix A (and Matrix B if needed).
2 Fill in the values in the grid inputs.
3 Select the desired operation from the buttons.
4 View the result matrix or scalar below the inputs.
5 For multiplication, expand the step-by-step section to see each dot-product calculation.
