About MatrixLab Exact
MatrixLab Exact is a local-first matrix calculator built for students who need mathematically trustworthy results, especially during row reduction and fraction-heavy work.
Why exact fractions matter
Many matrix tools quietly switch to floating-point approximations. This project keeps finite decimals and fractions exact internally, so intermediate steps stay faithful to the underlying algebra.
Current scope
- Matrix arithmetic and scalar multiplication
- Transpose, trace, determinant, inverse, RREF, and rank
- Linear system solving for unique, inconsistent, and infinite-solution detection
- Copy/export options and example presets
