9. The functions rea1max and rea1min give the largest and smallest possible numbers that can be handled by MATLAB. Calculations generating numbers that are too large or too small result in overflow and underflow. Usually this does not present a problem if you arrange the calculation sequence properly. Type realmax and realmin in MATLAB to determine the upper and lower limits for your system. For example, suppose you have the variables a=310150,b=510200. a. Use MATLAB to calculate c=ab. Page 45 b. Suppose d=510200, use MATLAB to calculate f=d/a. c. Use MATLAB to calculate the product x=abd two ways, i) by calculating the product directly as x=abdd and then ii) by splitting up the calculation as y=bd and then x=ay. Compare the results
