All interactive tools run entirely in your browser. Your data never leaves your device.
How It Works
Enter your matrix values (tab, comma, or space-separated, one row per line), select an operation, and see the result instantly. Binary operations (add, subtract, multiply) require a second matrix. The calculator uses LU decomposition for determinants and Gauss-Jordan elimination for inverses.
Features
- 9 operations: transpose, determinant, inverse, add, subtract, multiply, scalar multiply, trace, identity
- Flexible input: tab, comma, or space-separated values
- Up to 10x10 matrices: capped for performance
- Decimal and negative number support
- Error reporting: clear messages for dimension mismatches and singular matrices
- 5 examples: 2x2 determinant, 3x3 inverse, matrix multiply, transpose, scalar multiply
- Copy output: one-click copy of results
- Private: all computation runs in your browser — no data transmitted
Use Cases
- Linear algebra homework and verification
