lpc and hilbert functions

Iam getting an error with lpc :

 

error: `flag_implicit_skip_nan' undefined near line 119 column 5
error: if: error evaluating conditional _expression_
error: evaluating if command near line 119, column 2
error: evaluating if command near line 62, column 1
error: called from `sumskipnan' in file `/opt/octave/share/octave/2.1.50/site/m/octave-forge/NaN/sumskipnan.m'
error: called from `lattice' in file `/opt/octave/share/octave/2.1.50/site/m/octave-forge/tsa/lattice.m'
error: called from `lpc' in file `/opt/octave/share/octave/2.1.50/site/m/octave-forge/tsa/lpc.m'

 

Any ideas what I am doing wrong? Doesn't seem to matter what the input is.

Also with the hilbert function shouldn't this return a vector of cos(x) values if a vector of sin(x) values is input. Assume the x values are evenly spaced 0 to 2pi. Not sure I understand the output of this function. Any further explanation would be appreciated.
