|  |  D.6.9.7 sppairs Procedure from librarygmssing.lib(see  gmssing_lib).
 
Example:Usage:
sppairs(t); poly t
Assume:
characteristic 0; local degree ordering;
isolated critical point 0 of t
 
Return:
|  | list spp;  spectral pairs of t
  ideal spp[1];
    number spp[1][i];  V-filtration index of i-th spectral pair
  intvec spp[2];
    int spp[2][i];  weight filtration index of i-th spectral pair
  intvec spp[3];
    int spp[3][i];  multiplicity of i-th spectral pair
