Follow-up Comment #6, bug #41888 (project octave):
So it doesn't just mean that you have to explicitly give the value of that
parameter if you want to use the varargin? That's what it appears to do.
It's just like having multiple parameters with default values. If you want to
give the value of some later one, then you have to give the values for the
earlier ones (even if they're the same as the default).
So for instance, as a convoluted way to find the square root of some number y
function [z] = f(x,y)
z = abs(x .^ 2 - y);
function [r] = takesqrt(n)
r = fminsearch(@f, 1, struct(), n);
AFAICT, this works fine.
