Details:

This minimal example works under Octave 6.4.0 but throws an error in Octave
7.0.90 (plus, there are a couple of warnings when loading the optim package):


pkg load optim

x = (0:0.01:10).';
y = @(p) p(1) + p(2)*sin(2*pi*p(3)*x);

p0 = [0.3 0.5 0.2];
y0 = y([0.37 0.63 0.21]) + (rand(size(x))-0.5);

p_fit = lsqnonlin(@(p) y(p) - y0,p0);
plot(x,[y0,y(p_fit)])


I get this error:


error: : function called with too many inputs
error: called from

It seems to boil down to line 316 in \_\_nonlin_residmin\_\_


f.f = @ (varargin) f.f (varargin{:}) - obs;


which doesn’t seem to be allowed anymore.
