Index exceeds matrix dimensions

I've got a problem and because of my bad knowledge of matlab, it would be great if someone know the solution for this problem.

arr = {'01', '02', '03', '04'};

ldir = '/data/.....'

cond= {Forstats_1PLhann.mat};

savedir = ldir;

for i= 1:11;

display (sprintf('analysing subject....%s,arr{i}));

subjectdir=strcat(ldir, 'Tsbj_', arr{i},'/');

load(strcat(subjectdir,cond {1}));

data{1,i} = ft_freqdescriptives ([], PLhann);

clear PLhann

end;

cond= {Forstats3_PLhann.mat'};

for i = 12:22

display (sprintf('analysing subject....%s,arr{i}));

subjectdir=strcat(ldir, 'Tsbj_', arr{i},'/');

load(strcat(subjectdir,cond {1}));

data{1,i} = ft_freqdescriptives ([], PLhann);

clear PLhann end;

Please post the complete error message (do not trim the error message).

your array only contains four elements (first line of your code) in your loop you are trying to acces arr{i} where i goes from 1:11 this gives you the error message that the index exceeds matrix dimensions when the loop goes to i=5 because arr{5} does not exist so you have to change

for i = 1:4

OR define

arr = {'01', '02', '03', '04','05','06','07','08','09','10','11'};

depending on which one is applicable for your case
