Generation of random formal series

Description

Generation of random formal series with coefficients and exponents of variables from uniform discrete distribution.

Usage

1
rfseries(var, cf, k, m)

Arguments

var

number of variables of formal series

cf

number of generating coefficients

k

the greater parameter in U[0,k] distribution

m

the greater parameter in U[0,m] distribution

Details

The exponents of variables are generate from discrete uniform distribution U[0,k]. The coefficients are from U[0,m] but additionally multiply by -1 or 1 with equal probability.
