= Interval exchange transformation
{wiki=Interval_exchange_transformation}
An **interval exchange transformation** (IET) is a mathematical concept used in the field of dynamical systems and ergodic theory. It involves a way of rearranging segments of an interval (typically the unit interval \\(\[0, 1\]\\)) by applying a transformation that is defined by splitting the interval into several subintervals of specific lengths, then permuting those subintervals according to a specific rule.
