dir and filesep matlab

I am trying to find a list of jpg files but also using filesep (to break the names of the files) in one line

dir([folder,[filesep '*.' 'jpg']]).

The above command works for me. But I also want to find the files that include in their name a specific word like 'blue' but when I tried to use

dir([folder,[filesep '*.' '*blue*jpg']])

it did not work, the program does not find any files at all. Is there anyway to do this in one line? Thank you.

Why don't you use fullfile? This command will take care of the filesep for you in a much nicer way:

dir( fullfile( folder, '*blue*.jpg' ) );

You want to use dir([folder,[filesep '*blue*.jpg']]), or more simply dir([folder filesep '*blue*.jpg']).

Just to be clear, the * character acts as a "wildcard". It can represent zero or more characters of any kind.

*.jpg finds all .jpg files because * allows the filename before the extension to be anything.

red*.jpg finds all .jpg files starting with red, like redhouse.jpg or redflower.jpg.

*green.jpg finds all .jpg files ending with green, like grassgreen.jpg or darkgreen.jpg

*blue*.jpg finds all .jpg files that contain the word blue, like skyblue.jpg, bluecar.jpg, or mybluebox.jpg.

What you're using now, dir([folder,[filesep '*.' '*blue*jpg']]) would find files like something.BLAHblueBLEHjpg.
