Re: eigs.m problem in Octave 3.2.2

[Tatsuro MATSUOKA]

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
