getNumObjectives - Return number of objectives per label

Syntax

nobj = getNumObjectives(optimstore)
nobj = getNumObjectives(optimstore, objlabels)

Description

Return the number of objectives per label. A method of cgoptimstore.

nobj = getNumObjectives(optimstore) returns the number of objectives that will be returned from an evaluation of each objective label. For example, consider an optimization that has a sum objective over a set of points, S, and a point objective to be evaluated at each member of S. nobj will return [1 r], where r is the number of points in S.

nobj = getNumObjectives(optimstore, objlabels) returns the number of objectives that will be returned for the defined objective labels.
