D.15.7.3 multIdeals
Procedure from library hodge.lib (see hodge_lib).
- Usage:
- multIdeals(f, [, eng]); f a reduced poly, eng an optional integer.
- Return:
- list
- Purpose:
- compute the multiplier ideals of a hypersurface
.
- Note:
- The value of
eng controls the algorithm used for Groebner basis computations.
See the engine procedure from dmodapp_lib for the available algorithms.
- Display:
- If
printlevel =1, progress debug messages will be printed.
Example:
| LIB "hodge.lib";
ring R = 0,(x,y),dp;
poly f = y^2-x^3;
multIdeals(f);
