Re: New to Octave...

[Tristan Quaife]

Vincent,

Ben has already supplied you with an fine answer, but I thought
I'd add a suggestion. If you can get hold of Kurt Hornik's
octave-ci package, it supplies you with a function called
aload which allows you to directly load in data files without
the octave header information. Your script would then become:

file_in=input("Enter the full name of the input file? ", "s");
var=aload(file_in);
l=length(var); 
b=fft(var);

You can get octave-ci from:

ftp://ftp.ci.tuwien.ac.at/pub/octave/octave-ci.tar.gz. 

Hope this helps,

Tristan.
