Hi,
In the below script, I need to store the output kkkk into a new array but in the same column. Here, size of the kkkk is different during each itertaion.
I know that cell array would solve the issue. But I need to store them in the single colum.
for i=1:4
kkkk = find(A>=sz(i,1) & A<=sz(i,1)+100);
clear kkkk
end

kkk=cell(4,1);
for i=1:4
kkkk{i} = find(A>=sz(i,1) & A<=sz(i,1)+100);
end
kkkk=vertcat(kkkk{:});

I corrected the varibale name and preallocated the cell array correctly. Still the processing time is very large.
If you profile the code, I think you will see that the bottleneck is coming from find(), not from anything else. It's an expensive function.
