Hello,

I am looking to loop through a few files names that differ only by one letter, i.e they go 001a, 001b, 001c etc.

What is the simplest way to put set the loop up, so that it changes the value of the letter each time.

For example ideally i want:

For x=a:z

filename = ['001' ,x '.txt']

Or something similar.

Can this be done?

Kind regards

Joe Harris

Apologies if the question isn't worded very well!

Here's one way:

s = char(97:122) % Or just use: s = 'abcdefghijklmnopqrstuvwxyz';
for ns = 1:length(s)
      filename = ['001',s(ns),'.txt']
end

Also, 'a':'z'

will create the above string.

Now it's easier.

for letter='a':'z'
  filename = ['001', letter,'.txt']
end
