Write a MATLAB program that uses the Trapezoidal rule integration algorithm to determine the integral:

It is the integral from 0 to x of (x/sigma^2)*e^(-x^2/(2sigma^2)) dx

(4sigma^2=2, sigma^2=1/2)

Plot the equation (with x normalized to sigma^2 ) in the integral for x ranging from 0 to 4sigma^2

Use values for the integral limit for x of 0 and 2

Compare this with the exact value. (Hint: the integral should be 0 at x=0).

Cannot use MATLAB code, must create Trapezoidal in line function
