Write a well-commented Matlab function program mydblsimp that computes the Simpsons rule approximation. Let it call the program mydblsimpweights (above) to make the weight matrix, w (24.2). Check the program on the integral in the previous problem using (m,n) = (10,18) and (m, n)

I got the code but it is missing something I don't know what

a,b function I = mydblsimp (f, a,b,c,d, m, n) $a function that compute simpson rule -- define the interval in X, namely a
