markovRing(...,VariableName=>...) -- symbol used for indeterminates in a ring of discrete joint probability distributions



The indeterminates in the polynomial ring made by markovRing are labeled with the letter ''p'' suggesting probability distributions. However, it is useful to be able to create a new ring where the indeterminates are labeled different (for example, they may represent marginal probabilities).

i1 : d=(1,2);
i2 : markovRing (d,VariableName => q);
i3 : gens oo

o3 = {q   , q   }
       1,1   1,2

o3 : List
