Then A[I] is equivalent to an array of the first 10 elements of A. A practical example of this is a sorting operation such as: I = array_sort(A); % Obtain a list of sort indices B = A[I]; % B is the sorted version of A C = A[array_sort(A)]; % Same as above but more concise.
The idea is to quickly exclude many points that would not be part of the convex hull anyway. This method is based on the following idea. Find the two points with the lowest and highest x-coordinates, and the two points with the lowest and highest y-coordinates. (Each of these operations takes O(n).)
In array languages, operations are generalized to apply to both scalars and arrays. Thus, a+b expresses the sum of two scalars if a and b are scalars, or the sum of two arrays if they are arrays. An array language simplifies programming but possibly at a cost known as the abstraction penalty.
Also a key is usually decomposed into two parts, referring to x and y coordinates. Therefore, a node contains the following information: four pointers: quad[‘NW’], quad[‘NE’], quad[‘SW’], and quad[‘SE’] point; which in turn contains: key; usually expressed as x, y coordinates; value; for example a name
String functions are used in computer programming languages to manipulate a string or query information about a string (some do both).. Most programming languages that have a string datatype will have some string functions although there may be other low-level ways within each language to handle strings directly.
The three teams with NBA All-Stars will be split up via a draft by honorary general managers Charles Barkley, Kenny Smith and Shaquille O’Neal. The draft will take place Feb. 6 on TNT.
Nearest-X: Objects are sorted by their first coordinate ("X") and then split into pages of the desired size. Packed Hilbert R-tree: variation of Nearest-X, but sorting using the Hilbert value of the center of a rectangle instead of using the X coordinate. There is no guarantee the pages will not overlap.
