Hi, I know I can do this with loops but there must be a nicer way.

basepath='/data/';
filebase='video_';
fileext='.avi';
files=['00a' '00b' '00c'];

I'd like the output to be the vector

['/data/video_00a.avi' '/data/video_00b.avi' '/data/video_00c.avi']
(although I'd also be happy with a vertical matrix.

Thanks Tom

Are you sure you don't want 'files' to be a cell array? Because the way you've defined files, it will just concatenate 00a, 00b, etc. as one string. Observe:

files=['00a' '00b' '00c']
% files = '00a00b00c'

This is probably less useful to you. Instead, define 'files' as:

files = {'00a', '00b', '00c'}

Here you go, Tom.

basepath = '/data/';
filebase = 'video_';
fileext  = '.avi';
files    = ['00a'; '00b'; '00c'];
n        = size(files,1);
horzcat(repmat(basepath,n,1), repmat(filebase,n,1), files, repmat(fileext,n,1))
