%% Anonymous Functions

%%
% Another way to perform the circle calculations is to use anonymous
% functions.
%
% This can be done directly at the command prompt (or in our current
% file).
%
% We type
circumference = @(r) 2*pi*r

%%
% and
area = @(r) pi*r.^2

%%
% Anonymous functions are evaluated like standard math functions.
%
% To get the circumference of a circle with radius 5 we use
circumference(5)

%%
% To get both values we use, e.g.,
circledata = [circumference(5); area(5)]

%%
% Vectorized usage:
circledata = [circumference([2 4 6]); area([2 4 6])]
