count elements falling within certain thresholds in array in matlab?

Question

I have a huge vector. I have to count values falling within certain ranges. the ranges are like 0-10, 10-20 etc. I have to count the number of values which fall in certain rang

Answer 1

Why not simply do something like this?

% Random data
m1 = 100*rand(1000,1);

%Count elements between 10 and 20
m2 = m1(m1>10 & m1<=20);
length(m2) %number of elements of m1 between 10 and 20

You can then put things in a loop

% Random data
m1 = 100*rand(1000,1);

nb_elements = zeros(10,1);

for k=1:length(nb_elements)
    temp = m1(m1>(10*k-10) & m1<=(10*k));
    nb_elements(k) = length(temp);
end 

Then nb_elements contains your data with nb_elements(1) for the 0-10 range, nb_elements(2) for the 10-20 range, etc...
