MATLAB: Write a user-defined function that plots a triangle and the circle that is inscribed inside the triangle, given the coordinates of its vertices. For the function name and arguments, use TriCirc (A, B, C). The input arguments are vectors with the x and y coordinates of the vertices, respectively. This function has no output arguments. Use the function with the points (2.6, 3.2), (11, 14.5), and (-2, 2.8).
