Write a MATLAB program to solve a differential equation as follows: a. The "Windkessel model" uses an electrical circuit analog to model blood flow within a vessel, as shown below where P represents blood pressure and Q represents blood flow rate: b. P dp dQ +RC+PL+RQ di dt -+ = dt Qin Q Q C L oooo R Electrical analog for blood flow in a compliant vessel. c. Write a MATLAB program using symbolic variables to solve the differential equation for in the figure shown above using two different input equations. The result should also be symbolic - no specific values are needed. You can ignore initial conditions for this problem. a. Input #1: Set the input (Q) equal to 0 b. Input #2: Set the input (Q) equal to "sin(2*pi*f*t)" where "f" is a symbolic variable representing frequency
