compute derivatives without evaluation in program?
I desire F1 := C2/(X+5) and want F2 to be the first derivative F2 := -C2/(X+5)^2. More generally, given an arbitrary F1(X), I'd like F2(X) to be symbolic function without the values of variables being substituted for as the derivative is being calculated.
Here is my test program. C2 is a list of numbers. EXPORT MYTEST() BEGIN F1 := EXPR("'C2/(X+5)'"); F2 := EXPR("'diff(F1(X),X)'"); END; |
