Rank deficient error.

I am trying to evaluate a function on some points. When I put in the points manually one by one there is no problem but as soon as I put the values as a vector Im getting the following error:

Warning: Rank deficient, rank = 0, tol = inf.

my code looks like this:

gm=@(k) sqrt((par.sg.*k.^3+(par.rho2-par.rho1)*par.g.*k)/(par.rho1*coth(k.*par.h1)+par.rho2*coth(k.*par.h2)));
k1=linspace(0,100);
gr=real(gm(k1));
gi=imag(gm(k1));

Thanks in advance :)

Are you attempting to do matrix division? if not use ./ instead.
