fpica under octave

[j8a]

My name is Javier Ochoa, I am working at PROIMI in Argentina. I have installed Octave 2.9.12 under  Linux in order to run the ica routines you modified from the ones in MatLab written by Hurri et al.
I cannot run the fpica.m function because the following error message appeared:error: `all_va_args' undefined near line 100 column 13
Could anybody tell me where is the problem, I could not explain this and I will very appreciate your coments.
Best regards,

octave:13:> x=demosig
octave:14>[E,D]=pcamat(x)
octave:15> [nv,vm,dwm]=whitenv(x,E,D)
octave:16>[A,W]=fpica(nv,vm,dwm,'defl',4,'pow3','off',1,1,1,'off',1e-6,500,100,'rand',1,'rand','signals',20,'on','classic')
Used approach [ defl ].

Most probably, you try to run old style Octave code.
Previously the 'va_arg' method allowed a variable number
of input arguments to Octave functions (m-files).

Unfortunately some maintainers removed this feature
around Octave Version 2.1.56 without providing
any backwards compatibility :(

I'm afraid that you have to modify your functions
by hand using the modern 'varargin' functions
(see manual under multiple number of input arguments)
in order to run it in a later version of Octave.
