  Overrides:
    `start` in class `DefaultFieldMatrixPreservingVisitor<Fraction>`
  Parameters:
    `rows` - number of rows of the matrix
    `columns` - number of columns of the matrix
    `startRow` - Initial row index
    `endRow` - Final row index (inclusive)
    `startColumn` - Initial column index
    `endColumn` - Final column index (inclusive)

### visit

    public void visit(int row,
                      int column,
                      Fraction value)

  Visit one matrix entry.

  Specified by:
    `visit` in interface `FieldMatrixPreservingVisitor<Fraction>`
  Overrides:
    `visit` in class `DefaultFieldMatrixPreservingVisitor<Fraction>`
  Parameters:
    `row` - row index of the entry
    `column` - column index of the entry
    `value` - current value of the entry

### getConvertedMatrix
