5.1.63 leadexp

Syntax:

leadexp ( poly_expression )
leadexp ( vector_expression )

Type:

intvec

Purpose:

returns the exponent vector of the leading monomial of a polynomial or a vector. In the case of a vector the last component is the index in the vector.

Example:

ring r=32003,(x,y,z),(c,ds); poly f=x2+y+z3; vector v=[2*x^10,f]; leadexp(f); → 0,1,0 leadexp(v); → 10,0,0,1 leadexp(0); → 0,0,0
