L.S.
I'm trying to create a variable name dynamically, using the procedure in
example 1 below. Performing operations with the duynamically created
variable works as expected, as the same example shows.
However, I'm in a slightly different situation (example 2), where x
itself is a variable bearing an assumption. Now, the trick doesn't work
anymore. I can't perform operations with the dynamically created
variable because it apparently means something different now.
Is it possible in situation/example 2, to create a dynamic variable Dx
using the character x?
If so, can you show me how?
If not, is there a workaround?
Thanks in advance,
Erik Leunissen.
------------------- Example 1 -------------
> restart;
> Dx-D.x;
0
------------------- Example 2 -------------
> restart;assume(x>0);
> Dx-D.x;
Dx - Dx~
------------ End of examples ----------------
