gridmesh does not work for my case, why?

having u and v arrays of different sizes (54x1 and 61x1), I attempted to run the following;

function F = fcn(u,v)

[U,V]=meshgrid(u,v);

F= 1/((U.^(-0.66667))+(V.^(-0.6667)));

G=F.^(3/2);

surf(U,V,G)

3rd row did not work and says the following; "matrix dimensions must agree" ?!

what did I make wrong?

You need to use element-wise division as well in defining F

u = rand(54,1);
v = rand(61,1);

[U,V]=meshgrid(u,v);
%   v
F= 1./((U.^(-0.66667))+(V.^(-0.6667)));
G=F.^(3/2);
surf(U,V,G)
