% For integers k=-10,-9,....,9,10, the function k^2-50 will take positive as
% well as negative values.  For example, for k=-9, k^2-50=31; for k=1,
% k^2-50=-49; for k=8, k^2-50=14.
% The loop below will calculate values of k^2-50 for all values of k.

for k=-10:1:10
    val=k^2-50;
end

% Let's suppose you are asked to calculate value of k^2-50 for
% k=-10,-9,...,9,10 only until k^2-50 becomes negative.
