My script is this:
r=linspace(-180,180,360);
t=linspace(-180,180,360);
[R,T]=meshgrid(r,t);
phi_=6*r*cos(1+5^2/R.^2)-T;
contour(R,T,phi_)
but matlab throws the following error: Error using / Matrix dimensions must agree.
What am i doing wrong?

Ran in:
Use ./
r=linspace(-180,180,360);
t=linspace(-180,180,360);
[R,T]=meshgrid(r,t);
% phi_=6*r*cos(1+5^2/R.^2)-T;
phi_=6*r*cos(1+5^2./R.^2)-T;
contour(R,T,phi_)

You're welcome!
As @Star Strider points out, you probably intend to use .* as well, but using / instead of ./ is what caused the error.
