ufn

unconstrained tool, function evaluation.

Calling Sequence

F = ufn(X)

Parameters

X

real vector, variables of the problem

F

objective function evaluated at X

Description

ufn evaluates the objective function of the problem decoded into OUTSDIF.d at the point X, in the case where the only possible constraints are bound constraints.

Examples

sifdecode(get_sif_path()+'sif/AKIVA.SIF',TMPDIR+'/AKIVA')
buildprob(TMPDIR+'/AKIVA')
[X,BL,BU] = usetup(TMPDIR+'/AKIVA/OUTSDIF.d');

x = linspace(-1,0.1,30);y=linspace(-2,2,50);
function z=f(x, y),z=ufn([x;y]),endfunction

clf();
plot3d(x,y,feval(x,y,f)/100,theta=92,alpha=37)
