I've made a change to the CVS to support this. Note,
however, that s= struct() only works in newer versions
of octave (works in 2.9.2 and not in 2.1.42 - I don't
have others lying around to test)
setfields now reads:
function s = setfields(s,varargin)
if nargin == 0
s= struct; % doesn't work on older versions of octave
elseif rem(nargin,2) != 1,
error('setfields: expected struct, key1, val1, key2, val2, ...\n') ;
endif
for i=1:2:nargin-1
if ! isstr(varargin{i}) ,
error('setfields: called with non-string key') ;
else
eval( ['s.',varargin{i},'=varargin{i+1};'] ) ;
end
end
end

OK.
I encountered this because optimset.m has the line 45:
opt = setfields ();
which caused the original setfields.m:
function s = setfields(s,varargin)
if rem(nargin,2) != 1,
error('setfields: called with odd number of arguments\n') ;
endif
to complain.
nargin==0 should be a valid call to setfields, so maybe some easy fix
would be:
function s = setfields(s,varargin)
if nargin>0
if rem(nargin,2) != 1,
error('setfields: called with even number of arguments\n') ;
endif
else
s=struct;
end
