Method Summary

boolean	reduce() Reduce the whole matrix, that is, divide numerators/denominators by their greatest common divisor
boolean	reduceRow(int row) Reduce the specified row, that is, divide numerators/denominators by their greatest common divisor
boolean	reduceValueAt(int row, int col) Reduce the specified value, that is, divide numerator/denominator by their greatest common divisor

Method Detail

reduce

boolean reduce()

Reduce the whole matrix, that is, divide numerators/denominators by their greatest common divisor

Returns:

true if any value has been changed in the matrix

reduceRow

boolean reduceRow(int row)

Reduce the specified row, that is, divide numerators/denominators by their greatest common divisor

Returns:

true if any value has been changed in the given row

reduceValueAt

boolean reduceValueAt(int row,
                      int col)

Reduce the specified value, that is, divide numerator/denominator by their greatest common divisor

Returns:

true if the value has been changed
