Write a MATLAB M-file to compute the double integral below using the composite trapezoidal rule with h = 0.1 in both the x- and y-directions. You may use the MATLAB built-in function"trapz" (or the "trap.m" discussed in class and available Canvas) in your M-file. Check youranswer using the "dblquad" function. Provide a printout of your M-file and a printout of the command window showing your results. ∫(-2 to 2) ∫(0 to 3) (x^4-3xy+6y^2) dxdy
