在 MATLAB Online 中打开

p=polyshape(yourPoints);
area(p)
perimeter(p)
centroid(p)

在 MATLAB Online 中打开

function [ TriSPC ] = spcs(x)
% "C" won't give me coordinates
% How can i have coordinates of Center area?
x=input('Enter your Coordinates');
p=polyshape(x);
S=area(p);
P=perimeter(p);
C=centroid(p);
disp('area is:'), disp(S);
disp('Perimeter is:'), disp(P);
disp('Centriod is:'), disp(C);
end

If you use the second output of boundary() then it will return the area.

The coordinates of the center of a set of 2D points, is the same as the mean() of each of the coordinates -- unless there is a non-uniform "weight" associated with the coordinates (for example if the core is denser then the edges.)

I do not know what "environment" means for the purpose of your question ?
