OpenOpt is a free MATLAB Toolbox, which is also run in Octave


OpenOpt is a free MATLAB Toolbox, which is also run in Octave

Particularly, it contains non-smooth solvers
ralg (medium-scale, for nVars=1...1000)
ShorEllipsoid (small-scale, for nVars=1...10)
(both can handle lb, ub, Ax<=b, Aeq*x=beq, c(x)<=0, h(x)=0; providing gradients/sub gradients df, dc, dh is appreciated)

nonSmoothSolve - fsolve analog for nonsmooth & noisy funcs (try benchmarking in nonSmoothSolveEx.m).

Graphics output is also enabled (for Octave users still there are some problems).

2 lines are enough to solve your problem -
prob = ooAssign (ObjFun, x0, <optional params>)
r = ooRun (prob, solver)
Example of output structure r:
xf: [10x1 double] % x final
ff: -0.0719 % fval final
alg: 'Kennedy J., Eberhart R.C. (1995): Particle swarm optimization. In: Proc.'
author: 'Alexandros Leontitsis, me00743-at-cc.uoi.gr, University of Ioannina, Greece'
(+some other fields)
