HI Isabel,
You wanted to have submatrices which are having columns spread by 200 each. This can be done with a for loop as such:
x = randi([0 100],4,1000); % Arandom matrix of size 4 x 1000
tmp = cell(1,200);
for i = 1:200
tmp{i} = x(:,i:200:end);
end
% Each cell of tmp contains a submatrix which are the columns spread by 200
% each
% For example submatrix 2 can be known with tmp{2}
Hope this helps.
Please do post your upcoming questions in english to reach out wider audience.
Thanking you.
Regards,
Sriram
