if (~isempty(F_Zero)) %There is Zeros (not empty)
W(:,F_Zero) = []; % Remove the columns of W
HT(F_Zero,:) = []; % Remove the rows of HT
W_bar = W./sqrt(sum(abs(W.^2),1));
D_Matrix = HT*W_bar; %Diagonal Matrix
D_Square = (abs(diag(D_Matrix))').^2; % Channel gains
P = waterfill(Pt,Pn./D_Square);
F_Zero=find(~P);
else
% do Nothing
end

If you are looking for a loop, you may go for while loop.
while ~isempty(F_Zero)
% Do what you want
end
