Details:

I tried do use princomp.


M = rand(1000,3);
princomp(M)


results in


error: 'r' undefined near line 103 column 51
error: invalid limit value in colon expression
error: evaluating argument list element number 1
error: called from:
error:   ~/octave/statistics-1.2.3/princomp.m at line 103, column 13


Note that I anonymised the path in the last line of the error message.

I looked in the file and found that r is really not initialised for nargout <
2.
