Making a Loop with Strings

371 views (last 30 days)
Hello all,
What is the quick way of shortening this code?
Thanks in advance for the help (I'm sure this one's not 'hard' but I don't know the 'easy' way--or anyway).
data_10_100_1=importdata('filename_2.txt');
data_10_100_2=importdata('filename_5.txt');
data_10_100_3=importdata('filename_9.txt');
data_10_100_4=importdata('filename_11.txt');
data_10_100_5=importdata('filename_14.txt');
data_10_100_6=importdata('filename_16.txt');
data_10_100_7=importdata('filename_17.txt');
data_10_100_8=importdata('filename_18.txt');
data_10_100_9=importdata('filename_20.txt');
data_10_100_10=importdata('filename_22.txt');
data_10_100_11=importdata('filename_23.txt');
data_10_100_12=importdata('filename_24.txt');
data_10_100_13=importdata('filename_28.txt');
data_10_100_14=importdata('filename_29.txt');
The answer will be something like:
x = [2 5 9 11 14 16 17 18 20 22 23 24 28 29];
for i =1:14;
data_10_100str2num(i) = importdata('filename_' num2str(x(i)) '.txt')
end; clear i
but this doesn't work... I'm not sure how to fix it. HOw do I make that LHS correct (the RHS is probably also wrong..)
Many thanks, M.A.B.

Use a cell array
x = [2 5 9 11 14 16 17 18 20 22 23 24 28 29];
for i =1:14;
data_10_100{i} = importdata(sprintf('filename_%d.txt',x(i)));
end;
