hi all,
I want to get the result of the C_Varactor value of VCO,so i used two equation to get it in the display windows:
1.C_Varactor =-1/(2*pi*freq[0,0]*imag(Z11[0]))
2.C_Varactor =-1/(2*pi*freq*imag(Z(1,1)))
But i get the different result.Why?what are the difference between freq[0,0] and freq, Z11[0] and Z(1,1)?

freq and Z11 are arrays. And Z11=Z(1,1). Z11[0] means Z11[frequnecy_index=0]
So the first equation will give C_Varactor values at frequency index 0, which is, the start frequency of the your simulation. The second equation will return an arrary of C_Varactor, while freq is one of the independent variables.
