    %% Test Complex Numbers  

%% 
% Create a vector of complex numbers. 
A = [1+i 2-2i 1+3i 1-2i 5-i];  

%% 
% Find the values that are less than or equal to |3|. 
A(A <= 3) 

%%
% |le| compares only the real part of the elements in |A|.  

%% 
% Use |abs| to find which elements are within a radius of |3| from the
% origin.
A(abs(A) <= 3) 

%%
% The result has one less element. The element |1.0000 + 3.0000i| is not
% within a radius of |3| from the origin.
