Description
|
|
|
•
|
The command rgf_norm(Fz, z) puts the generating function in normal form, expands the numerator and denominator, and factors the low order coefficient from the denominator.
|
|
•
|
If the optional 'factored' argument is used, the function factor is applied to the denominator.
|
|
•
|
The algebraic extensions ext may be a single extension, an expression sequence of extensions, or a set of extensions to be used when factoring the denominator.
|
|
•
|
The command with(genfunc,rgf_norm) allows the use of the abbreviated form of this command.
