5.1.78 leadmonom

Syntax:

leadmonom ( poly_expression )
leadmonom ( vector_expression )

Type:

the same as the input type

Purpose:

returns the leading monomial of a polynomial or a vector as a polynomial or vector whose coefficient is one.

Example:

ring r=32003,(x,y,z),(c,ds); poly f=2x2+3y+4z3; vector v=[0,2x10,f]; leadmonom(f); ==> y leadmonom(v); ==> [0,x10] leadmonom(0); ==> 0
