Reading Text File As Numbers

I'm working with MATLAB GUI.
So, I want users to browse their own table from their computer. When they have browsed, the full path will be written on the static text, and the table (that they browse) will be appeared.
The problem is, the file; it reads strings, not numbers.
So, how to read text file data as numbers and not string? What script do I have to write?
Thank you.

Posting such an unformatted pile of code is not useful. It is not readable and contains too many details without a relation to the original question.
In other words: The missing formatting of your code makes it impossible for me to check, if there is any relation to the question at all, which was: How to read a file as numbers, not as strings.
So please stop flooding the forum with large unrelated codes. Thanks.
