diffalg.Class
Return the class of a given derivative.
Syntax
$diffalg.Class(X:INDET):INT
Description
The function Class returns the class of derivative X, i.e., the index of the differential indeterminate of which it is a derivative.
Example
Use Q[x[1..2,0..20]]; $diffalg.Class(x[1,8]); ------------------------------- 1 ------------------------------- Use Q[x[1..2,0..20]]; $diffalg.Class(x[2,8]); ------------------------------- 2 -------------------------------
