optimsimplex_xbar

Returns the center of n vertices.

Syntax

cen = optimsimplex_xbar(opt, iexcl)

Argument

opt

The current simplex object of TSIMPLEX type (tlist).

iexcl

The index of the vertex to exclude in center computation. The default value of iexcl is the number of vertices: in that case, if the simplex is sorted in increasing function value order, the worst vertex is excluded.

cen

A row vector.

Description

The optimsimplex_xbar function returns the center of n vertices, by excluding the vertex with index iexcl.

Example

s1 = optimsimplex_new ();
simplex = [
3.      -1      1
4.      -3      2
5.      4       5
];
s1 = optimsimplex_setall ( s1 , simplex );
cen = optimsimplex_xbar ( s1 );
disp(cen)

s1 = optimsimplex_destroy(s1);
