Detailed Description

Replace elements with normalized rank.

Each element x is replaced by $\frac{\sum I(x_i-x) w_i}{\sum w_i}$ where $ I(x) = 1 $ for $ x>0 $ , $I(x) = 0.5 $ for $ x=0 $ , and $ I(x) = 0 $ for $ x<0 $ .

Since: New in yat 0.5

	)		const

inline

It is possible to centralize a range "in place"; it is permissible for the iterators first and result to be the same.

Type Requirements:

RandomAccessIter1 is Random Access Traversal Iterator
RandomAccessIter1 is Data Iterator
RandomAccessIter2 is Writable Iterator
RandomAccessIter2 is Random Access Traversal Iterator
RandomAccessIter2 is Data Iterator
