That is a nice one! But in the doc it says
"If A is a matrix, then max(A) treats the columns of A as vectors and returns a row vector of largest elements."
So you maybe want to do something else? Like
[a,ix]=max(out(:,2))

Thanks it worked for me.....
Can you please guide in this scenario..
out = [a,histc(idx(:),a)]; % out variable having cluster number and cluster size
[a,ix]= max(out(:,2)); %getting the max value in a and its index in ix variable
[row , col] = find(idx ==ix);%using find func in checking where in idx the ix exists and storing the row col index in row and col
mx_row = max(row); %getting max row index
mx_col = max(col);%getting max col index
for i = 1 : mx_row %for loop till max row index
for j = 1 : mx_col %for loop till max col index
cp = I(row(i),col(j));% getting the row and col indexes and accessing the element from I and store it in cp
end
end
There is error for loops it is not storing the values at corresponding locations.. Can you please guide where i m having error on the above following code???

If you can provide data and code together, that is easier for me to help. Otherwise I need to make guesses.
