Problem 1 (20 points) Write a Matlab function EquivR such that EquivR (Values, 'S') returns the equivalent resistance of any number of resistors in series (the second argument 's' stands for "series). The resistor values are stored in Values, a one-dimensional array. EquivR (Values, 'P') returns the equivalent resistance of any number of resistors in parallel ('P' stands for parallel). The resistor values are stored in values, a one-dimensional array. Include this code with your report
