Sorting via x9 is not guaranteed to get results to match--points with the same x value but different y values can be flipped by roundoff errors in x.
OK, thanks. I think the new test will avoid that problem.
Has the test actually changed? Sorry to make extra work for you....
I thought I had changed it, but it wasn't changed. Now it is. Thanks again. I appreciate the feedback.
The new test didn't work for me, but the following seems like it might do the trick:
[~,indx]=sort(angle(complex(x9-x0,y9-y0)));
X9=x9(indx);
Y9=y9(indx);
[~,indx]=sort(angle(complex(x9_correct-x0,y9_correct-y0)));
x9_correct=x9_correct(indx);
y9_correct=y9_correct(indx);
OK, thanks Tim. I changed the test.
Thank you.
