    well...I have a PV(photovoltaic) system and i want to solve it with Runge Kutta-4 method.I have some questions.... 1)Is there any program to solve RK-4? 2)I have the differential equations dIt=(I_f-It)/(Cf*(R2-R)),where R=(((-Ns)*Rs/Np)-(Ns/L*((Il*Np)-(It(i))+(Np*Io)))) dI_f=(Ep-VCf)/(Lw+Lf)...
