Find the rank of a matrix and see every row-reduction step. Exact fractions, no rounding. Dimensions up to 6×6.
Enter the entries of matrix A — whole numbers, decimals, and fractions like 1/2 are all accepted.
Pick the rows and columns for A, from 1×1 up to 6×6. Rank is defined for any rectangular matrix, not just square ones.
Type a value into each cell. The result updates as you type, and every value is kept as an exact fraction rather than a rounded decimal.
The rank and row-echelon form appear first, followed by every row operation used to reach it — swaps, scalings, and eliminations.
