Thank you for use my intsolver and point some issues on it. I observed that you found some problems which make Intsolver works improperly. I will work on that and post a correction as soon as possible.

free (even for commercial usage) solver interalg (http://openopt.org/interalg) seems to work tens-hundreds-thousands times faster and is more stable, the bench is provided there.
Excuse me,I've Intlab and insolver in my machine, I've a problems with Insolver, I want to solve a nolinear system of equations with intksolve.m, and intksolve.m, because the result isn't an interval, it's solution of real numers not intervals. see this:
>> x0 = [infsup(-10,10), infsup(-10,10), infsup(-10,10), infsup(-10,10)];
f = @(x) [-2*(x(1)+x(2)-x(3)-1)-2*(x(1)+x(2))-10*x(1)+2*x(4),-2*(x(1)+x(2)-x(3)-1)-2*(x(1)+x(2)),2*(x(1)+x(2)-x(3)-1)+x(4), 2*x(1)+x(3)]
x = intksolve(f, x0)
f =
@(x) [-2*(x(1)+x(2)-x(3)-1)-2*(x(1)+x(2))-10*x(1)+2*x(4),-2*(x(1)+x(2)-x(3)-1)-2*(x(1)+x(2)),2*(x(1)+x(2)-x(3)-1)+x(4), 2*x(1)+x(3)]
intval x =
0.1428 0.2142 -0.2857 0.7142
I need to obtain the interval solution of x(1),x(2)... x(4)
What I have to do?
I need the article of hansen& greenberg for information about your implementation (intsolve) for free thanks
Dear Dmitrey,
Thank you for use my intsolver and point some issues on it. I observed that you found some problems which make Intsolver works improperly. I will work on that and post a correction as soon as possible.
