How to generate polat plot for 4 variables

I would like to generate polar scatter plot for 4 variables (aspect, elevation, slope, area), where:

aspect - represent angular axis

elevation - represent radial axis (the distance from the center)

slope - represent the color of plot (grading color)

area - represent the size of dots

After typing the code (attached below) in Matlab R2014b I have the following error: Undefined function 'polarscatter' for input arguments of type 'double'. Does anybody know what can be wrong?

clear; clc; close;
D = [500.0 450.0 600.0 350.0]; % Elevation
S = [5.0 40.0 25.0 15.0]; % Slope
AS = [25.0 225.0 15.0 60.0]; % Aspect
A = [100.0 55.0 70.0 20.0]; % Area

polarscatter(AS,D,A,S,'filled');

You need R2016b for polarscatter().

Thank you for the answer. Do you know is there any other function which I could use to get similar results to polarscatter?

[José-Luis]

You can use scatter(). It should not be that difficult to transform polar coordinates to cartesian coordinates. Matlab even has cart2pol() and pol2cart() to help you.
