M-files are usually text files, which contain Matlab commands. It is a bad idea to fill an M-file with some numbers only. Most of all load is not sufficient to read your data file. Better use fopen and fscanf and skip the lines, which you want to ignore.

In addition:

You could also use csv files (comma-separated) and use readcsv and so on. Those Matlab functions already come with the extra of only reading certain rows/columns/areas.
