Determinant calculation by expanding it on a line or a column, using Laplace's formula
This page allows to find the determinant of a matrix using row reduction, expansion by minors, or Leibniz formula.
- Leave extra cells empty to enter non-square matrices.
- You can use decimal (finite and periodic) fractions:
1/3,3.14,-1.3(56), or1.2e-4; or arithmetic expressions:2/3+3*(10-4),(1+x)/y^2,2^0.5 (=),2^(1/3),2^n,sin(phi), orcos(3.142rad). - Use ↵ Enter, Space, ←↑↓→, ⌫, and Delete to navigate between cells, Ctrl⌘ Cmd+C/Ctrl⌘ Cmd+V to copy/paste matrices.
- Drag-and-drop matrices from the results, or even from/to a text editor.
- To learn more about matrices use Wikipedia.
