$(30$pts$)$ Write a script that calls three separate functions to accomplish three tasks:

A function get$3$points$()$ to prompt the user for three pairs of coordinates and returns $x$ and Y vectors. The coordinates need to be input as two vectors respectively of all Xs and three points are all different.

A function calc$(x,Y)$ to calculate and retum the central point of the three points, $[$ xc yc $].($The method to calculate the central point of three different points mathematically is:

$(\frac{1}{3^{**}}(x1+x2+x3),\frac{1}{3^{**}}(y1+y2+y3))$

A function printit $)$ to print the results in the exact format with I decimal place precision:

The central point of $(x1,y1)(x2,y2)(x3,y3)$ is $(xc,yc.$

Note: the solution to this problem involves four code files: one acting as a main script and three for the function. $($write your code on next page$)$ matlab
