please provide matlab code

Let the excitation for both circuits shown below be e(t) 10 Vu(t). Plot the voltage vo(t), the reactive voltage (the voltage across the reactive element assuming the left terminal is positive) and the reactive current (the current flowing through the reactive element from left to right) for the two circuits using either Matlab or Mathcad. Plot these circuit variables as t varies from 0 to two time constants for the circuits. Label the values of these circuit variables on the plots at times t 1 time constant and t 2 time constants. The values of the circuit components are Ri-4.3 k2, R2- 2002, R 4 C 2 e(t) (t Circuit1 Ww 4 2 e(t) Circuit 2
