    %% Cross Product of Vectors  

%% 
% Create two 3-D vectors. 
A = [4 -2 1];
B = [1 -1 3];  

%% 
% Find the cross product of |A| and |B|. The result, |C|, is a vector that
% is perpendicular to both |A| and |B|.
C = cross(A,B) 

%% 
% Use dot products to verify that |C| is perpendicular to |A| and |B|. 
dot(C,A)==0 & dot(C,B)==0 

%%
% The result is logical |1| (|true|).
