Create a matlab program to compute the magnitude and phase angle of the impedance(Z) of an RLC series circuit.

Given:

R= 2(resistance in ohms)

L=4e-3(inductance in henries)

C= 10e-6 (capacitance in farads)

Z= R + ((w*L)-(1/(w*C)))*i (impedance in V/A)

:Create a vector of angular frequencies from 1000 1/s to 10000 1/s in steps of 250.

:Create a Z vector for each frequency

:Create a vector containing the magnitude of Z for each frequency

:Create a vector containing the phase angle of Z for each frequency

:Comput the resonant frequency w0 = 1/sqrt(L*C)

:Present results in table and graphs

You have your formulae, you just need to make them work.

angular_freqs = 1000:250:10000;

.* and ./ do elementwise multiplication and division.

 A = [1;2;3;4;5]; B = -A; 
[A B]  % makes a table get printed out

plot(A,B) %plots "B" on the y axis and A on the x axis, of a graph.

Any more help than that is me doing your homework for you.
