This a fairly common typical notation that indicates the size and shape of an array, as well as the datatype. So here, a double precision array, with 441 rows and 2 columns.
Note that it is NOT legal MATLAB syntax though. If you tried to type that in an executable line in MATLAB, it would generate an error. So this is only valid as a comment. Of course, you can write anything you please in a comment. So if I type that line in:
>> x = [441x2 double]
x = [441x2 double]

Error: Unexpected MATLAB expression.
As expected, an error results, as it must.
