Got to write this function for a homework assignment. The function is meant to take in input arguments G,C,w and z and produce the voltage magnitude and phase angle as the output. My professor gave us a general idea of what the function should look like but I am still having trouble figuring out how to write it. Below is what I have so far. Am I missing anything?
function [mag,phase]=bode1(G,C,z,w);
f = [0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1 2 3 4 5 6 7 8 9 10 20 30 40 50 60 70 80 90 100 200 300 400 500 600 700 800 900 1000];
a = [1 2 3 4 5 6 7 8 9];
z = [0.1a a 10a 100a 1000a];
w0 = 2*pi*f
x = [v1; v2; v3; v4; v5; v6; v7; v8];
y = x*(w0)
mag = [];
phase = [];
mag[mag abs(x)];
phase[phase angle(x)];
v = mag(1,;) ;
end

Do you have the equations for voltage magnitude and phase angle that the professor wants you to use (in terms of G, C, w, and z)?

Other than my previous comment, you need multiplication signs between your values and a:
z = [0.1a a 10a...
should be
z = [0.1*a a 10*a...
and I'm not sure what to make of your last few lines just yet, but given the equations, I can probably provide some useful hints.

Do you know what the z is useful for?

That sounds reasonable, assuming (G+jwC) is invertible. But make sure you write
x = A\w
not
x = A/w
