# MPolyCatPolyFactorizer(E, OV, R, PPR)¶

This package exports a factor operation for multivariate polynomials with coefficients which are polynomials over some ring R over which we can factor. It is used internally by packages such as the solve package which need to work with polynomials in a specific set of variables with coefficients which are polynomials in all the other variables.
factor(p) factors a polynomial with polynomial coefficients.
