compute_p_distance {gor}

Distance-p between two-dimensional points

Description

It computes the distance-p between two-dimensional points.

Usage

compute_p_distance(x, y, p = 2)

Arguments

x

A two-dimensional point

y

A two-dimensional point

p

The p-parameter of the distance-p

Details

The distance-p is defined by

d_p(x,y) = \left(\sum_i (x_i-y_i)^p\right)^{\frac{1}{p}}

.

Value

The distance-p between points x and y.
