Hi, I have a set of data with 10000 rows and 6 columns. I need to plot every 100 rows with 6 columns automatically. I appreciate it if any one can help me. Many thanks Siavash

Hi Siavash,
could you please specify your problem? Are the data stored in 10000x6 matrix? Do you want to plot the 100x6 data? Sorry, I can not understand yours problem.

data = rand(10000, 6);
for i= 1:10
i1 = (i-1)*100 + 1;
i2 = i1+100 - 1;
subplot(2,5,i), plot(data(i1:i2,:)')
end
or remove the transpose operator ', depending on what you want to plot
subplot(2,5,i), plot(data(i1:i2,:))

A=rand(1000,6) % ------Example---
%you can use cell array or 3-D matrix
B=mat2cell(A,100*ones(10,1),6)
%Then use a for loop to do your plot
for k=1:numel(B)
a=B{k}
% do what you want with a 100x6 matrix a
end
You can also, use a 3-D matrix
A=rand(1000,6)
B=permute(reshape(A',6,1000,[]),[2 1 3])
