About this tool
Find the determinant, inverse, transpose, rank or trace, or add, subtract and multiply matrices up to 8 × 8.
Determinant and rank use Gaussian elimination with partial pivoting; the inverse comes from Gauss–Jordan elimination of [A | I]. Products follow the row-by-column rule.
Formula: det A, A⁻¹, Aᵀ, A·B
Example: Matrix A = 2 1 1 3, Operation = Determinant of A → Result = 5.
Write one row per line with numbers separated by spaces, e.g. “1 2” then “3 4”. Results are rounded to 12 significant digits.
Quick steps
- Enter your values — every field shows its unit.
- Press Calculate (or Try an example to see how it works).
- Read the results and copy them if you need them elsewhere.
The calculation runs in your browser. Nothing you type is sent to 1CLIK.
