Neighboring distance of data points

Calculate the distance between neighboring data points

File name : 'ndistance.m'. This file can be used
for calculating the distance between neighbouring data
points based on Pythagoras theory:
d = sqrt((X(l+1)-X(l)).^2+(Y(l+1)-Y(l)).^2)

or in short:

d = sqrt((dX).^2+(dY).^2))

Four input values: 'X', 'Y'
One output value: 'D'

X = vector of x-values
Y = vector of y-values

D = distance between two neighbouring data points
Additionally, a plot of the distance against the Y-vector
will be generated

Input syntax: d = ndistance(X,Y)
