I get an error when I try to access that link. Attach your file to your Question here using the ‘paperclip’ icon, and be sure to complete both the ‘Choose file’ and ‘Attach file’ steps.

Depending on the way your file is formatted and what it contains, use either the csvread or xlsread functions. Another option is the textscan function.
