Details:

When calling polyfit with a value for n of larger than 0, e.g. polyfit([0 1
2],[0 1 4], 2), I get the following error:
error: qr: subscript indices must be either positive integers less than 2^63
or logicals
error: called from:
error:   /opt/octave3.8/share/octave/3.8.1/m/polynomial/polyfit.m at line 114,
column 10

The error does not occur if I just want to estimate the constant term, e.g.
polyfit([0 1 2],[0 1 4], 0), but for anything larger than 0 it produces the
error.
