> Where "18-10" is the date when they were created, and the other one ex. "1-26" is the hour and minute. I want to process only the .mat files that are between two given start and stop time, in the order that they were created. I'm blocked because I don't know how to query those in the name of the files. If I do a "dir" command in matlab it will give me a structural variable that has information about every file when it was created in a string format, and I don't know if matlab can calculate time comparison. I was thinking of making a matrix with all the files that meet the criteria and then invoke them to read the data from them.

use regexp to decipher which filenames u want.
extract all the filenames using "dir" and "name" field
for i = 1:number of files
if (regexp(decipher file name) is what I want)
process the file
end
end
if the filenames have consistent names, u can also use strcmp or strncmp instead of regexp
