uofg

unconstrained tool, evaluation of function and possibly gradient.

Calling Sequence

[F,G] = uofg(X)

Parameters

X

real vector, variables of the problem

F

value of the objective function at the point X.

G

real vector, gradient of the objective function at the point X.

Description

The uofg subroutine evaluates the value of the objective function of the current SIF problem (see usetup) at the point X, and possibly its gradient in the case where the only possible constraints are bound constraints.

[X,BL,BU]=usetup(TMPDIR+'/AKIVA/OUTSDIF.d');

[f,g]=uofg(X)
X=[-0.053109827466;-0.237575444849];
[f,g]=uofg(X)
