Hello,
there is an equation for solving Energy stored in a Capacitor. That's an easy equation. But, I want to write that solving equation in matlab. Would you please tell me how to solve that equation in matlab. Solving equation is given below:
Energy stored in a Capacitor = 0.5 * C * (Vfinal^2 - Vinitial^2)
= 0.5 * 31 * (320^2-310^2)
= 15.5 * (102400-96100)
= 15.5 * 6300
= 97650
Thank you very much.

I am not certain exactly what you want.
See if this works —
C = 31
C = 31
Vinitial = 310
Vinitial = 310
Vfinal = 320
Vfinal = 320
Energy_stored_in_a_Capacitor = 0.5 * C * (Vfinal^2 - Vinitial^2)
Energy_stored_in_a_Capacitor = 97650
.
