Re: problems reading fits file

[Poulette Poulette]

ok ! I didn't understand that "pkg" was an octave function.

The fits install seems to be ok now, but I still have the same problem:

error: 'read_fits_image' undefined near line 5 column 8

Here is my little code:

# pca compute
clear all

addpath('/Users/me/')
data = "">

covariance = cov(data');

The "pkg" command is one of Octave's core functions.  If you don't have that function, then something is seriously wrong with your installation.  From Octave's prompt, what does "which pkg" return?
