Tīmeklisthe rank of a right child = rank of the parent + 1 + number of elements in its left subtree. It can be used to find any general i t h order statistic in the BST in O (h) time, i.e. O (log n) time if the tree is balanced. So it is useful to find the median of the elements or ith largest/smallest element among the elements. Share Cite Follow TīmeklisDefinition 1.10. (The identity matrix). The n × n matrix I = [ δij ], defined by δij = 1 if i = j, δij = 0 if i ≠ j, is called the n × n identity matrix of order n. In other words, the columns of the identity matrix of order n are the vectors. For example, and The identity matrix plays a critical role in linear algebra.

This corresponds to the maximal number of linearly independent columns of A. This, in turn, is identical to the dimension of the vector space spanned by its rows. Rank is thus a measure of the "nondegenerateness" of the system of linear equations and linear transformation encoded by A. There are multiple equivalent definitions of rank.
