How to edit each matrices in a cell?

Hello,

I have a 50x27 matrix that contains values between 0 and 55. I have been trying to create seperate matrices dependant on intervals of the matrix values. For example, I want to create matrix A that contains all the values between 0 and 5. Then matrix B that contains values between 5 and 10. Matrix C between 10 and 15...and so on. I have started the code below. NTG_MeanEmpty is a 50x27 matrix with values between 0 and 55.

L1 = 0:5:50;

L2 = 5:5:55;

n = 10;

Analysis = cell(n, 1);

for k = 1:n;

for m = 1:10;

for i = 1:50;

for j = 1:27;

if NTG_MeanEmpty(i,j) >= L1(1,m) & NTG_MeanEmpty(i,j) < L2(1,m);

Analysis{k,1}(i,j) = 1;

else Analysis{k,1}(i,j) = 0;

end

end

end

end

end

When I run the code it seems that the matrices contained within the 10x1 cell are not populated with any data. Please could you advise on any errors in this code, or suggest an alternative method?

Thank you.

L1 = 0:5:50;
L2 = 5:5:55;  % By the way, these are 11 values, not 10
NTG_MeanEmpty = randi([0, 55], 50, 27);
n = 11;
Analysis = cell(n, 1);
for k = 1:n
   m = (NTG_MeanEmpty >= L1(k) & NTG_MeanEmpty < L2(k));
   Analysis{k} = m;  % Perhaps
   % Or:
   % tmp = zeros(50, 27);
   % tmp(m) = NTG_MeanEmpty(m);
   % Analysis{k} = tmp;
end

That worked! Thank you very much! :)
