What's the best way to read an ASCII/txt file containing a few lines of text and then the data I want to load into a matrix?

I will have files converted to something like this:
Pad 1:1 /This is what the converter writes out /Not sure if it will have the same number of comments every time /information /more text
0.0 14.666
0.2 134.567
0.3 1567.435
... ...
and so forth. I want to read only the numerical data into a matrix to later work with and prefer it to not be a hack job, and something that will consistently read in many files. Thanks!

If you always have the same number of header lines, use TEXTSCAN and set the parameter 'HeaderLines' to a relevant value, e.g. 2 if you have two lines of header in each file.
In the example that you provided, it seems that you have have a line of text, an empty line, and then numbers, so you should be able to work with something like:
fid = fopen( 'myFile.txt', 'r' ) ;
data = textscan( fid, '%f%f', 'HeaderLines', 2 ) ;
fclose( fid ) ;
