Problem with dimensions using meshgrid

Not sure why my code isn't working

    >> [x,y]=meshgrid(-100:1:100, -100:1:100)
    >> z = (-4.3461.*(10.^-7)).*[1/[1 + ((x.^2)./(30^2))].^1.5];
    Error using  / 
    Matrix dimensions must agree.

You need to vectorise every multiplication, division, and exponentiation:

z = (-4.3461.*(10.^-7)).*[1./[1 + ((x.^2)./(30^2))].^1.5];
                           ↑  VECTORISE HERE AS WELL
