DA.Class
Returns the class of a given derivative.
Syntax
DA.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.
@param X Indeterminate for which the class is computed.
@return The class of indeterminate X.
Example
Use QQ[x[1..2,0..20]]; DA.Class(x[2,8]); ------------------------------- 2 -------------------------------
