    %% Sum of Elements in Each Column  
% Create a |fi| array, and compute the sum of the elements in each column.   

%%  
A=fi([1 2 8;3 7 0;1 2 2])  

%%  
S=sum(A) 

%%
% MATLAB(R) returns a row vector with the sums of each column of |A|. The
% |WordLength| of |S| has increased by two bits because |ceil(log2(size(A,1)))=2|.
% The |FractionLength| remains the same because the default setting of |SumMode|
% is |FullPrecision|.
