degree of polynomial matrix

Syntax

D = degree(M)

Arguments

M

polynomial matrix

D

integer matrix

Description

returns the matrix of highest degrees of M.

Examples

v=[-2-5*%s+%s^2;-6+11*%s-6*%s^2+%s^3];
degree(v) // should return 2 and 3

s=poly(0,"s");
p=1+s+2*s^42;
degree(p) // should return 42
