Thanks for this new release.
When running the tests in csaps, some warnings are issued:
octave:1> x = ([1:10 10.5 11.3])'; y = sin(x);
octave:2> csaps(x,[y 2*y],1,x)';
warning: quotient: automatic broadcasting operation applied
warning: quotient: automatic broadcasting operation applied
warning: product: automatic broadcasting operation applied
warning: product: automatic broadcasting operation applied
The warnings come from the following lines in csaps.m:
dd(2:n, :) = diff(cc(2:(n+1), :)) ./ h;
bb(2:n, :) = diff(a) ./ h - (cc(2:n, :)/2).*h - (dd(2:n,:)/6).*(h.^2);
Since the messages may be confusing for the casual user, the code could
be wrapped like this:
warn_state = warning ("query", "Octave:broadcast").state;
warning ("off", "Octave:broadcast");
unwind_protect
dd(2:n, :) = diff(cc(2:(n+1), :)) ./ h;
bb(2:n, :) = diff(a) ./ h - (cc(2:n, :)/2).*h - (dd(2:n, :)/6).*(h.^2);
unwind_protect_cleanup
warning (warn_state, "Octave:broadcast");
end_unwind_protect
Cheers,
