Description

• 

The function wdegree computes the degree of an expression, considered as a form.

• 

The function wdegree returns nonhmg when the expression is a sum of forms which have different degrees.

• 

Expressions of type scalar or const have wdegree = 0.

• 

The wdegree of an indexed name is the wdegree of the name without the index, unless explicitly stated.

• 

The command with(difforms,wdegree) allows the use of the abbreviated form of this command.
