Dear all,
Some time ago I asked a question on maple primes concerning handling the numeric solutions of dsolve procedure.

They sent me to the discussion on option remember and indeed this helped a lot.
However there is another issue.

The method I am trying to implement requires iterative calls to dsolve/numeric with one of the functions defined from the previous...

One useful feature of the `evalf` command is that it remembers previous results. But it also stores the current value of Digits as well as its input argument, to be associated with the remembered result.

There are two reasons for this. The fancier reason is so that, when Digits is reduced from that of an earlier successful computation, `evalf` can simply round off the earlier result to the desired number of decimal digits. The more basic reason is that `evalf` might...

please help me here

we want a "remember table assignment for the first derivative evaluated at a point a1" for example

D(f)(a1):=0

but using this command maple creates a proc

for example using the command

f(a1):=0:

maple asks : 1. function def. 2. remember table assignment

but using D(f)(a1) :=0 just creates a function def.
