Creating arrays for plotting purposes

Good day! I am experiencing difficulties creating an array to use for plotting: you see, I've created my variable array - the "x" of the whole plotting operation, but now I'm trying to plug that into my function and it's not resulting in a new array, just a scalar output. I've tried adding dots to just about every operator, doesn't seem to do a whole lot of good.

Here are the relevant lines of my code:

R1=10^4:100:5*10^5;
R2=10^3;
C=10^-10;
w=13.56*10^6;

Z=sqrt(((R1.*R2).^2+(R1./(w*C)).^2)/((R1+R2).^2+1/(w*C)^2));

And that last line is the problem. I can't seem to get it to form an array! I would greatly appreciate any advice on the matter.

Z = sqrt(((R1.*R2).^2+(R1./(w*C)).^2)./((R1+R2).^2+1/(w*C)^2));
                                     ^^ you need to use RDIVIDE, not MRDIVIDE!

Hawk's eyes you've got! Thank you very much, I will be reading the articles for bedtime tonight. Seems to me, the way to go is to just plop dots on every questionable operator until I get better at the language!

If you are not doing linear algebra then use the dots.
