- solve system of linear equations using Gauss-Jordan elimination
- infinite precision rational numbers (solve anything using exact arithmetics!)
- up to 10x10 matrices supported, add/remove columns/rows on the fly
- input decimal or rational number (10.5 or 22/7 for example)
- three display modes: decimal, rational, mixed (5/4 will be displayed as 1 1/4)
- two matrix memory slots (A, B)
- AxB, BxA, A+B, A-B, B-A operate on memory slots
- 100 undo levels
- calculate inverse matrix, adjoint matrix, determinant, trace, rank
- standard Gaussian elimination supported as well
- transpose
- randomize
- find nice integral matrices whose inverse is also integral (up to 6x6 supported) (RandInv function)
- change cell font size or cell width
- one-click clear with zeroes or load with identity matrix
- easy to use
- optimized for Retina display
