a question about ops{} command

Hi; I've wrote a mfile in which a symbolic variable is produced that its length is more than 25000 characters, so I broke it by using "ops" and it breaks the variable in 369 expressions. Now I need to get the derivative of the sum of these expressions. What could I do? Is there any way to save all of these expressions? Thanks

Consider using the MuPAD map() operation.

feval(symengine, 'map', YourSymbolicExpression, 'diff', TheDerivativeVariable, 'Unsimplified')
I would, however, expect that
diff(YourSymbolicExpression, TheDerivativeVariable)
would do just as well.
The 25000 character limitation applies to *displaying* a variable, not to storing it.
