Arith: Arith methods for hyperdirichlet objects

In hyperdirichlet: A Generalization of the Dirichlet Distribution

Description

Methods for Arithmetic functions on hyperdirichlet objects. There are only two operations:

• Add two of the same dimensions, as in ‘a+b’

• Multiply a hyperdirichlet object by a length-one scalar, as in ‘a*5’

Both these operations result in the normalization constant becoming unknown.

No unary operations are defined.

Value

Arithmetic functions on hyperdirichlet objects return hyperdirichlet objects. Multiplication operates on the powers (not parameters), thus it is defined so that a+a = 2*a = a*2; associativity means that a+...+a (n copies) equals n*a.

Note

The package delegates ‘a+b’ to hd_add(), which the user should use if more control is desired.
