Update of bug #57982 (project octave):
Item Group: None => Regression
_______________________________________________________
Follow-up Comment #2:
The same test works with version 1.5.1 of the package
(need to run it manually as there are no tests in 1.5.1):
## independents
indep = 1:5;
## objective function:
f = @ (p) sumsq (p(1) * exp (p(2) * indep) - [1, 2, 4, 7, 14]);
## initial values:
init = [.25; .25];
## linear constraints, A.' * parametervector + B >= 0
A = [1; -1]; B = 0; # p(1) >= p(2);
settings = optimset ("inequc", {A, B});
assert (nonlin_min (f, init, settings), [.6203; .6203], .0001);
so I am marking this as a regression.
