Is there anything in Advanced Analysis Library for finding radius of a circle given an (x,y) point on the circle?

I am trying to find a radius of curvature of a part of a circle. There is a mathematical equation to do this, but hard to code. I have (x,y) point along the circle,but need to find the radius based on these points. Any ideas?

There is nothing in the CVI Analysis library for this. There isn't much in the Analysis library for geometric calculations since it is primarily designed to help with test and measurement types of analysis.

It really isn't a complicated thing to do in basic math though. You would need three points on the circle to find the circle. Here is a link to a description of the math involved: http://mcraefamily.com/MathHelp/GeometryConicSectionCircleEquationGivenThreePoints.htm.
