Polynomials
Every integer, real, double-precision or complex vector corresponds to a descending polynomial . In addition, if it is a column vector, it corresponds to a polynomial stored in ascending order. Some of the routines below operate on polynomials stored in ascending order while others operate on polynomials stored in descending order. The routine reverse can be used to convert from one ordering to the other.
