%function [mu,sig,p] = cifar_10_bayes_learn1(f, trlabel,N)
%trlabel=tr_labels(1:100)';
label=[1:10,2:11,3:12];
%N=16;
mu = zeros(10,(N*3));
%sig = zeros(10,3) %task1
sig = zeros((N*3),(N*3),10); %task2
p = zeros(10,1);
for i = 1:10
[row] = (find(label==i));
%[row] = find(trlabel==i-1)
for j=1:N
mu(i,j) = mean(f((row(i,j))));
mu(i,j+N) = mean(f((row(i,j+N))));
mu(i,(j+(2*N))) = mean(f((row(i,(j+(2*N))))));
end
mu(i,:)=[mu(i,j),mu(i,j+N),mu(i,(j+(2*N)))] %error in this, suscripted assignment dimension mismatch
% sig(:,:,i) = cov(f((row),:))
% %Sig(:,:,i)=(cov(f(row))+cov(f(row),:).')/2;
% p(i) = (length(row) / length(f))
end
end
The above code has to return 10 values in row vector,ie, the first index of unique values.The row values should be displayed as 1,2,3,...,10. I wanted to calculate mean,sigma for that particular indexed rows in training data.

We have no idea what the above code is supposed to do since it's not commented. In addition, it's littered with unnecessary brackets making it harder to read (in my opinion), e.g. the line
mu(i,(j+(2*N))) = mean(f((row(i,(j+(2*N))))));
is simply
mu(i, j+2*N) = mean(f(row(i, j+2*N)));
You should explain the problem you're trying to solve in details, rather than giving us uncommented code that may or may not work.
