The algorithm shown below estimates the value of

${\displaystyle \underset{a}{\overset{b}{}}}f(x)dx$

using the composite traperoid rule with $n$ equally or unequally spaced base points $(x_i,y_i)$a$)$ Represent the algorithm as a flow chart.b$)$ Write a Matlab function program TrapRule $($x$,$y$,$n$)$ which implements this algorithm and returns the estimated value of the integral to the calling program.c$)$ Write a Matlab program which calls the function program developed in part $($b$)$ to evaluate the integral
