> ------------------------------------------------------------------
>
> Key: MATH-1075
> URL: https://issues.apache.org/jira/browse/MATH-1075
> Project: Commons Math
> Issue Type: Improvement
> Reporter: Axel Kramer
> Priority: Minor
> Attachments: FieldReducedRowEchelonForm.java

>
> Matrix class that wraps a FieldMatrix<T> matrix, which should be transformed to reduced row echelon format.
> See: http://en.wikipedia.org/wiki/Row_echelon_form
> Example:
> RowReduce({{2, 0, -1, 0, 0},{1, 0, 0, -1, 0},{3, 0, 0, -2, -1},{0, 1, 0, 0, -2},{0, 1, -1, 0, 0}})
> gives:
> {{1,0,0,0,-1},
> {0,1,0,0,-2},
> {0,0,1,0,-2},
> {0,0,0,1,-1},
> {0,0,0,0,0}}
