How can I plot this?

produce a plot of V for characteristic impedance values ranging from Z0 = 0.01; 0.1; 1; 10; 100; 1000; 10000 and for values of ZL = 1x10^-3 to 1x10^6. Use a step size for ZL of 1. Plot your results on a Semi-logarithmic plot with the horizontal axis as the log scale. You should have 1 plot with 7 curves on it. where V = (ZL - Z0 / ZL + Z0)

I wrote this code:

ZL = 10^-3:1:10^6;
Z0 = [0.01, 0.1, 1, 10, 100, 1000, 10000];
V = (ZL - Z0)/(ZL+Z0);

I got this: matrix dimensions must agree

I used .- and .+

it said wrong operator

hint:

(1:2).' + (3:5)

hint: .+ and .- do not exist as operators, but ./ does.

Use a for loop:

Here's a start.

ZL = 10^-3:1:10^6
Z0 = [0.01, 0.1, 1, 10, 100, 1000, 10000]
for k = 1 : length(Z0)
	thisZ0 = Z0(k);
	V = (ZL - thisZ0) ./     etc.
	plot(.....etc.
	hold on
end

See if you can finish it.

it worked thanks, can i do the scaling inside the loop?

[Image Analyst]

Sure. Or use semilogx().
