difforms

 formpart
 find part of an expression which is a form

 Calling Sequence formpart(expr)

Parameters

 expr - any Maple expression, but usually a product

Description

 • The function formpart is most effective on products.  It will try to simplify other expressions to products.
 • This function removes scalars and constants from a product, leaving only that part which is a form, or is undeclared.
 • This function and scalarpart can be used to separate a product into form and scalar parts.
 • The command with(difforms,formpart) allows the use of the abbreviated form of this command.

Examples

 > $\mathrm{with}\left(\mathrm{difforms}\right):$$\mathrm{defform}\left(f=\mathrm{scalar}\right)$
 > $\mathrm{formpart}\left(2\left(fv\right)&^u\right)$
