FixedPoint

Usage

• FixedPoint[f, expr] starts with expr, then applies f repeatedly until the result no longer changes.

Notes

• FixedPoint[f, expr, n] stops after at most n steps.

• FixedPoint always returns the last result it gets.

• You can use Throw to exit from FixedPoint before it is finished.

• FixedPoint[f, expr] applies SameQ to successive pairs of results to determine whether a fixed point has been reached.

• NestWhile[f, expr, comp, 2] provides a way to use a general comparison function.
