polydec

Compute polytopic coordinates with respect to box corners

Syntax

vertx = polydec(PV)
[C,vertx] = polydec(PV,P)

Description

vertx = polydec(PV) takes an uncertain parameter vector PV taking values ranging in a box, and returns the corners or vertices of the box as columns of the matrix vertx.

[C,vertx] = polydec(PV,P) takes an uncertain parameter vector PV and a value P of the parameter vector PV, and returns the convex decomposition C of P over the set VERTX of box corners:

P = c1*VERTX(:,1) + ... + cn*VERTX(:,n)
cj >=0 ,              c1 + ... + cn = 1

The list vertx of corners can be obtained directly by typing

vertx = polydec(PV)
