18. Write a user-defined function that determines the location of the center and the radius of a circle that passes through three given points in a plane. The function also creates a plot that shows the circle and the points. For the function name and arguments, use [C R]=Circle3Pts(A,B,C). The input arguments A, B, and C are each a two-element vector with the x and y coordinates of the corresponding point. The output argument C, is a vector with the coordinates of the center the output argument R, is the radius (both rounded to the nearest hundredth). Use the function with the following three points: A(7, 1.2), B(0.5, 2.6), and C(–2.4, –1.4).
