Chapter 7, Problem 16P

To determine

(a)

A user-defined MATLAB function that calculates the circumference of a triangle for the given coordinates of the vertices using $\text{[cr] = cirtriangle(A,B,C)}$ as function name and arguments (Write the code of $\text{cirtriangle}$ such that it has a sub-function or an anonymous function for calculating the distance between two points); the circumference of triangle with the following vertices $A\text{ =}\left(\text{ 1, 2}\right)$, $B\text{ = }\left(\text{10, 3}\right)$ and $C\text{ = }\left(\text{6, 11}\right)$.
