MATLAB: How can i create figures in a for loop

Question

I have to create a figure every 80 measurements of a row vector with length 31999 (Bn in the code). I tried to write this code but i receive only one figure with all the measurements (31999):

k= length(Bn);
for i= 1:80:(k-1)
    Bn1(i) = L(i);
    plot(Bn1);
end

any suggestion?

Answer 1

Try this:

repts = fix(numel(Bn)/80);
for k1 = 1:repts
    figure(k1)
    idxrng = (1:80) + 80*(k1-1);
    plot(Bn(idxrng), L(idxrng))
    grid
end
