polyMatrix (version 0.3.1)

degree.polyMatrix: The degree of a polynomial or a polynomial matrix

Description

The degree of the highest non-zero coefficient of the given polynomials.

Usage

# S3 method for polynomial
degree(p, …)
  # S3 method for polyMatrix
degree(p, …)

Arguments

p

a polynomial or polyMatrix class object

…

~~~~

Value

When the input is a polynomial class object, then value is the degree of the polynom.

When the input is a polyMatrix class object, then is the maximum of the degree of all polynoms.

Method degree_matrix returns a matrix by the same size as the input, containing the degrees of the polynomials.

And methods degree_column and degree_row returns of the columns or rows of the polynom matrix degrees.
