RREF Calculator
Compute the reduced row echelon form (RREF) of a matrix using exact rational arithmetic. Supports fractions and decimals.
Formula
Gaussian elimination with partial pivoting over exact rational numbers to reach reduced row echelon form.
Assumptions
- Matrix entries are parsed as exact rational values where possible.
Limitations
- Very large entries may exceed practical display limits.
- Row operation steps are not shown — only the final RREF matrix.
Worked example
2×2 identity
The 2×2 identity matrix is already in RREF: [[1, 0], [0, 1]].
Frequently asked questions
What matrix sizes are supported?
Up to 6 rows and 8 columns. Common sizes like 2×2, 3×3, and augmented 3×4 are supported.
