Do it in MatLab and please show the code.

3. [15 pts] Create a function that performs numerical integration three ways (i) Right-hand Riemann integral (ii) Simpson's rule The inputs to the function will be: - The name of the function to be integrated - The left and right endpoints of integration - The (uniform) rectangle width (commonly known as h ). The outputs to the function will be the results of each of the two methods. Apply your function on each of the following: 03xexdx0sin(x)dx12lnxdx For the first of those three, you can use the function created in the previous exercise. You can refer to MATLAB's built-in functions for the other two integrands. For each of those three integrals, state the method and the results, as an output statement. If you cannot create the function, you may do only the integration, for partial credit
