P-1 Write a Matlab script to calculate the first order derivative of the attached engine pressure graph: a) Find P' (q ) using second order scheme with h = 0.5 for the whole domain b) Find P' (q ) using second order scheme for the first and last couple of nodes and fourth order scheme for the central nodes with h = 0.5. c) Plot the two graphs in the same figure for a domain of -140 to 130 degrees Hints: Use the appropriate differential schemes from the table in chapter 8. Remember that the number of records is: i = =(b-a/h) +1
