Consider this code

Y = rand(1000,100) ; 
iwant = zeros(20,50,100) ; 
uwant=zeros(50,1,100);
for i = 1:100
    Y1 = Y(:,i) ;
    S1  = numel(Y1);  % this is same always 1000
    iwant(:,:,i) = reshape(Y1(1:S1 - mod(S1, 20)), 20, []);
    uwant(:,:,i)  = sum(iwant(:,:,i), 1).' / 20; 
    A=uwant(:,:,1:100);
    B=abs(A-z);
    C=min(B,[],[2 3]);
end

C is 50 by 1. Each value in C is selected from each row of 100 variables. How can I know the location where C is taking from among the 100 variables
