新安装的mpt工具箱，为什么P = polytope还是不能识别

新安装的mpt工具箱，为什么P = polytope还是不能识别

extreme这个函数就可以得到顶点坐标。
给你个代码：
function irPoly = getIrreg(m,s)
%GETIRREGULAR Summary of this function goes here
% get irregular pixels
% the same begin & end
% clockwise order
% m - regular size
% S - low/high resolution

% get limit voronoi
x = gallery('uniformdata', [(m*s)^2 1], 0);
y = gallery('uniformdata', [(m*s)^2 1], 1);
vOut = [0,0; 0,m; m,m; m,0];
P = polytope(vOut);
Options.pbound = P;
% Options.plot = 1;
Pn = mpt_voronoi(m*[x,y],Options);

% split each polygon
for iPoly = 1:length(Pn)
thisPoly = extreme(Pn(iPoly));
% limited in [0,m]
thisPoly(thisPoly>m) = m;
thisPoly(thisPoly<0) = 0;
% make points in order
k = convhull(thisPoly(:,1), thisPoly(:,2));
% make clockwise
[pX,pY] = poly2cw(thisPoly(k,1),thisPoly(k,2));
irPoly{iPoly} = [pX,pY];
end%for iPoly
