I have this data set (attached). I tried to find the boundary for it but the boundary doesn't follow outer data points exactly (as shown) especially at the corners. Though I tried to change shrink factor(s). Hope you can help me figure that out.
Thank you
x=Data(:,1);
y=Data(:,2);
s=1; %shrink factor
k = boundary(x,y,1);
Xbound=x(k);
Ybound=y(k);
plot(Xbound,Ybound);

Try different shrink factors, the third argument. Try something between 0.1 and 0.9 until you find one that "hugs" your point set the best.
