error: `eig' undefined near line 5 column 7

[Rich Shepard]

  I'm brand-new at using octave. I need to calculate the principal
eigenvector for a symetrical matrix. For the moment, it's 8x8. The installed
version of octave is 2.1.35; I downloaded 2.1.71 yesterday but haven't yet
upgraded.

  I wrote a short shell script:

#! /usr/bin/octave -pf
# calculate eigenvector for Columbia Gateway scoping.
A = [1.000,0.143,0.333,9.000,0.167,0.200,0.500,0.250; 
7.000,1.000,0.200,9.000,0.333,0.143,5.000,4.000; 
3.000,5.000,1.000,5.000,0.250,0.167,1.000,3.000; 
0.111,0.111,0.200,1.000,0.143,0.125,0.125,0.200; 
6.000,3.000,4.000,7.000,1.000,2.000,0.500,4.000; 
5.000,7.000,6.000,8.000,0.500,1.000,0.333,0.333; 
2.000,0.200,1.000,8.000,2.000,3.000,1.000,1.000;
4.000,0.250,0.333,5.000,0.250,3.000,1.000,1.000];
foo = eig(A);

  When I run it this is what I see:

  What have I missed?

Thanks,
