I have two shapes and I want to color the area between them
The first shape is a circle of Radius R=10 for example and with center (0,0), and the second shape is a random shape but surrounds the cirle and may have communs points, but it is impossible to have points inside the circle (as in the picture).
As example for real data that I have:
load('data.mat'); % load the coordinates of the second random shape represented as 'xfs' and 'yfs'
%%%%%%%%% create the circle %%%%%%%%%%
R = 10; C = [0. 0.] ;
xcf = C(1)+R*cos(linspace(0,2*pi,length(xfs))) ;
ycf = C(2)+R*sin(linspace(0,2*pi,length(xfs))) ;

Let's plot it right now:
load(websave('t','https://www.mathworks.com/matlabcentral/answers/uploaded_files/592700/data.mat'))
scatter(xfs,yfs)

load(websave('t','https://www.mathworks.com/matlabcentral/answers/uploaded_files/592785/data.mat'))
R = 10; C = [0. 0.] ;
xcf = C(1)+R*cos(linspace(0,2*pi,length(xfs))) ;
ycf = C(2)+R*sin(linspace(0,2*pi,length(xfs))) ;
shpOuter=polyshape(xfs,yfs);
shpInner=polyshape(xcf,ycf);
plot(shpOuter,'FaceColor','none');
hold on
plot(shpInner,'FaceColor','none');
plot(subtract(shpOuter,shpInner))
hold off

No. You should upgrade. There have been lots of important new features added since R2016a.
