SYNTAX

d =  city_block_cvip( vector1, vector2)

Input Parameters include :

vector1 - Feature vector 1. A numeric row or column vector.
vector2 - Feature vector 2. A numeric row or column vector.

Output Parameter include:

d - cityblock distance between two vectors.

DESCRIPTION

This function calculates the city block or absolute value distance measure from the elements of the two arrays x and y.

The city block distance for two vector x, and y is defined as:

$|| x - y ||_1 = \sum_{i=1}^n |x_i - y_i|$

EXAMPLE

% input vectors

  vector1 = [1 3 4 2];

  vector2 = [-3 3.2 sqrt(2) pi];

% city block distance between two vectors.

  d =  city_block_cvip( vector1, vector2);
  fprintf('city block distance: %d', d);

city block distance: 7.927379e+00
