Value function approximation and collocation method

To measure the time, we can use hsec command in GAUSS. The keyword command

returns the hundredth of a second since midnight. We can count how much time

it takes in the following way:

new; cls;

dt0=hsec;

( program lines )

dt=hsec;

print dt-dt0;

or we could set

print (dt-dt0)/100;

in terms of seconds.
