LC |
Syntax |
LC(F:POLY or VECTOR):C where C is one of INT, RAT, or ZMOD. |
Summary |
the leading coefficient of a polynomial or vector |
Description |
This function returns the leading coefficient of F, as determined by the term-ordering of the ring to which F belongs. |
Example |
Use R ::= Q[x,y]; LC(x+3x^2-5y^2); 3 ------------------------------- LC(Vector(0,5y+6x^2,y^2)); 6 ------------------------------- |
