I need help putting this into MATLAB. Answer to A will be fine, and I can work the rest. Will upvote!

Set up your own 2D planar trilateration problem. Place the SVs at (0,300) (100,400), (700,400), and (800,300). Generate a range measurement for a base station at (400,0) and a user at (401,0). a. Solve for the position of the user using 2 SVs and then 4 SVs assuming no clock errors. How does the PDOP change for the two cases? b. Solve for the position of the user assuming you need to solve for the user clock bias. What is the PDOP with all 4 satellites. c. Calculate a differential solution between the base and user using a single difference model and assuming you must solve for a clock bias between the base station and user. What is the PDOP with all 4 satellites? d. Calculate a differential solution between the base and user using a double difference model to remove the clock bias between the base station and user. What is the PDOP with all 4 satellites? e. Assuming the range error is zero mean with unit variance, what is the order of accuracy in the above 4 solution methods?
