D.4.18.10 isprimaryMon
Procedure from librarymonomialideal.lib (see monomialideal_lib).
- Usage:
- isprimaryMon (I); I ideal
- Return:
- 1, if I is primary; 0, otherwise.
(returns -1 if I is not a monomial ideal) - Assume:
- I is a monomial ideal of the basering.
LIB "monomialideal.lib"; ring R = 0,(w,x,y,z,t),lp; ideal I = w^4,x^3,z^2,t^5,x*t,w*x^2*z; isprimaryMon (I); ==> 1 ideal J = w^4,x^3,z^2,t^5,x*t,w*x^2*z,y^3*t^3; isprimaryMon (J); ==> 0 |
