Matlab programming

1 Collinearity of Three Points You are going to create a function to test whether 3 points are collinear (lie in a straight line). This can be done by evaluating the area of the triangle formed by the points. Create a function with the following header: function [ collinear ] iscollinear( p1, p2, p3 ) where p1 is a 1 x 2 double array storing the x and y coordinates of point 1 p2 is a 1 x 2 double array storing the x and y coordinates of point 2 . p3 is a 1 x 2 double array storing the x and y coordinates of point 3 . collinear is a logical variable returning whether the points are collinear As part of your main function, you must create a sub-function as follows: function [ area ] triArea pi, p2, p3 ) where . pi is a 1 x 2 double array storing the x and y coordinates of point 1 . p2 is a 1 x 2 double array storing the x and y coordinates of point 2 . p3 is a 1x 2 double array storing the x and y coordinates of point 3 . area is the area of the triangle formed by points pl, p2 and p3 Note that for a triangle with vertices (xi, yi), (x2, ya) and (x3, ys), the area is given by 2 where |.] represents the absolute value of the determinant of the quantity inside the parenthesis. Make sure you are accounting for machine round-off errors in your code
