I can't find any Matlab functions of those names--nor is there any TMW NETCDF Toolbox listed at the TMW web site.
This must be either Octave maybe or something from File Exchange or a vendor package???
So far, it doesn't seem to be a Matlab question.

the 0 sized matrix means that non of the elements of f are greater than 30000, so if you want solve the problem, try this:
d=find(f>30000);
if any(d)
f(d)=nan;
end
