Hello
I have built octave-3.2.2 on MinGW( Windows)
octave.exe:13> n = 20;
octave.exe:14> k = 4;
octave.exe:15> A =
sparse([3:n,1:n,1:(n-2)],[1:(n-2),1:n,3:n],[ones(1,n-2),1:n,-ones(1,n-2)]);
octave.exe:16> d1 = eigs (A, k)
d1 =
19.407
18.407
18.096
17.096
For my binary, eigs.oct works correct. There is no 'eigs.m ' in octave 3.2.
The problem is not issue of octave 3.2.2 itself.
Perhaps you download your 0ctave 3.2.2 binaries from the package managing place
on your linux
distribution. If my guess is true, please ask at the ML of the application
distribution site.
If you have built your octave by yourself, please show the kind of linux
distribution (Redhat, Debial
etc.) and show configuration at the build process.
Regards
Tatsuro

Hi,
I installed Octave 3.2.2, when I do: help eigs, I can see its help information
as below, but
when I use it, it shows:
octave:16> a=[1 2 3;4 5 6;7 8 9];
octave:17> eigs(a)
error: eigs: not available in this version of Octave
octave:15> help eigs
`eigs' is a function from the file
/usr/local/libexec/octave/3.2.2/oct/i686-pc-linux-gnu/e
igs.oct
-- Loadable Function: D = eigs (A)
-- Loadable Function: D = eigs (A, K)
-- Loadable Function: D = eigs (A, K, SIGMA)
-- Loadable Function: D = eigs (A, K, SIGMA,OPTS)
......
Does anyone know what is the problem? Is Octave 3.2.2 already built with ARPACK
package?
Thanks a lot.
