i've tried to use the load function but the text at the top of the file creates an error. I cannot change the file as it is hardcoded into another software.
Any ideas?

A = textread( 'mydata.dat', '', 'headerlines', 1 );

Why not use the wizard and just ignore or delete textdata?
Here is an alternative to textread. Doc says: "textread will be removed in a future version. Use textscan instead."
I copied your sample to 'h:\m\cssm\cssm.dat'.
I prefer to give Headerlines the value 2. In case I redefine Whitespace. That is if there is an empty line between the header and the data.
fid = fopen( 'h:\m\cssm\cssm.dat', 'r' );
cac = textscan( fid, '', 'Headerlines', 2 );
fclose( fid );
