So, if your points are not known to lie in a good order to represent a polygon, we could convert to polar coordinates, and then sort the sequence of points around the centroid. Simpler is to just use a convex hull to do the heavy thinking for you. So if I swap...
and C is the hypotenuse.) If you're trying to find the hypotenuse, square the other sides, add them together and take the square root. If you're trying to find a side other than the hypotenuse, square the side given, subtract

I am using the code as given below to calculate the ellipses and rotate by an angle. But it is not rotated at given angle. Can anyone please help me to resolve this issue? %cov is 2x2 covariance matrix that is generated through a long process ...
(when the sun is exactly north-south in the sky – at its highest point). Place the loose end of the string at the end of the cast shadow and hold it taut. Use the protractor to measure the angle where the string meets the stick at the top. Have your partner do the same in her...

Polar scopes are usually 15 to at best 30mm diameter telescopes, are relatively uneasy to use (you have to crawl below the mount), and normally it's not so obvious to find the damned sigma octantis with them. Of course it is better to have your polar axis more or less at the latitude...
Some points to consider when selecting a location for aurora photography: Geographic Latitude: It would be ideal, although not necessary, to find a spot within the auroral belt. (According to Dr. Syun-Ichi Akasofu, this is the polar region where the aurora is visible about two-thirds of the...
Need to rotate an image in the frequency domain. It should be relatevely easy, since all you need to do is multiply indices by exp(i*angle). But this will work only is picture represented in polar coordinates. So the botlle neck for me currently is an ability to read the image ...
