Loglog plot not plotting anything

So I am trying to plot this log function, but nothing is being plotted on the graph. The figure pops up, but there is nothing on the figure. I know that it's mainly because my Zeq matrix values are getting NaN + NaNi but I am not sure how to fix that

My Code is below:

f = logspace(10, 10E9);
C1 = 2.33E-10; 
Cox = 4.77E-5;
C = 2.8E-15;
g2 = 1/(4*10^-3E-3)*(Cox).*f;
g1 = 1/(4*10^-3E-3)*(C).*f;
L1 = 0.0118;
r1 = 1.42;
r = 6.818E-6.*sqrt(f); 

s = 1i*2*pi.*f;

x = 1./((g2+(1./(s.*C1)).*(r1 + 1./(s.*Cox))) ./ (g2+(1./(s.*C1))+(r1 + 1./(s.*Cox))));
y = r + s.*L1 + ((g1./(g1.*s*C) + 1)); 
z = 1./y;
Zeq = 1./(x+z);
loglog(f,abs(Zeq));
grid on;

There is only 1 point that isn't an (inf,NaN) pair.

Your code works with my correction.

The logspace call is wrong.

If you want ‘f’ to go from 10 to , call it as:

f = logspace(1, 9, 50);

That creates a 50-element vector between those limits.
