mediansorted

Calculate the median value of a sorted array.

Installation

npm install @stdlib/stats-array-mediansorted

Usage

var mediansorted = require( '@stdlib/stats-array-mediansorted' );

mediansorted( x )

Computes the median value of a sorted array.

var x = [ 1.0, 2.0, 3.0 ];

var v = mediansorted( x );
// returns 2.0

x = [ 3.0, 2.0, 1.0 ];

v = mediansorted( x );
// returns 2.0

The function has the following parameters:

• x: input array.

Notes

• If provided an empty array, the function returns NaN.
• The function supports array-like objects having getter and setter accessors for array element access (e.g., @stdlib/array-base/accessor).

Examples

var linspace = require( '@stdlib/array-base-linspace' );
var mediansorted = require( '@stdlib/stats-array-mediansorted' );

var x = linspace( -50.0, 50.0, 10 );
console.log( x );

var v = mediansorted( x );
console.log( v );
