Calculation of Resonance Requency of an RLC circuit

Hi, I have the following RLC circuit. I try to find out the resonance frequency of the circuit. Can you please help me out to calculate the resonance frequency. Then, I can code it in matlab.

Please let me know. My calculated resonance frequency is given below. Please let me know, is it correct or not:

f= (1/2*pi) * sqrt((Rw(i)*Cw(i)*Ga+Ra*Rw(i)*Cw(i)+Ca+La+Cw(i))/(Lw(i)*Cw(i)*Ca+La*Lw(i)+Cw(i)));

Thanks.
