MATLAB RLC circuit demo code

	clc

	caps = [1, 2, 3, 4]; % put actual capacitor numbers here (Converted to SI units ie. Ferads)
	inductors = [1, 2, 3, 4]; % put inductor values here (Converted to SI units ie. Henrys)

	targetFrequency = 1200 * 10^3;

	for i = 1 : length(caps) % goes through elements in caps array
	for j = 1 : length(inductors) % goes through all inductors
	% run the amplitude function (the loops will take care of every combo)

	MAKING A PLAN

	A common problem solving model is known as input-process-output.

	1. What are the possible inputs I can expect to receive?
	2. How should each type of input be processed?
