% You must specify The upper and lower limits of the function where all
% values are zero. Look at the example code

% example code do not delete only comment out
if t < 0 || t > 3 % <- Notice how I specify the upper and lower limits beyond which all 
                  % values are zero. Let the upper limit correspond to
                  % Time_End_h variable that is in the time_parameters

    h = 0;
else
    h = 1.5*t;
