Hi,

This may be a silly question but I have not found an answer to it yet
in the Documentation Centre.

In dynamic programming the following construct


  f [ x_, y_] := f [x,y] =  ......

is used, unless I am mistaken.

I'd like to know if there are other situations where we must write a
function definition in the above format.

Thanks in advance.

Kind Regards.

Sid.
