Matrix Calculator

• Free online matrix calculator supporting addition, subtraction, multiplication, scalar multiplication, determinant, inverse, transpose, rank, trace, matrix power, eigenvalues/eigenvectors, LU decomposition, QR decomposition and more

1. Open the tool page — no installation needed
2. Pick a category and operation (e.g. addition, multiplication, determinant), fill in matrix A (and matrix B for binary ops) in the grid, and set its dimensions (2–8) plus any scalar/exponent
3. Click "Calculate" to get the result; use "Copy" to grab it, "Load Example" to fill sample matrices, or "Reset" to clear

• This tool is completely free and requires no sign-up
• Everything runs locally in your browser — your data never leaves your device
