D.6.12.4 KScoef
Procedure from library kskernel.lib (see kskernel_lib).
- Return:
- exports ring RC and number C within it. C is
the coefficient of the word defined in the list qq,
being a part of C[i,j] for x^p+y^q
Example:
| | LIB "kskernel.lib";
int p=5; int q=14;
int i=2; int j=9;
list L;
ring r=0,x,dp;
number c;
L[1]=3; L[2]=1; L[3]=3; L[4]=2;
KScoef(i,j,p,q,L);
c=imap(RC,C);
c;
==> 27/8575
L[1]=3; L[2]=1; L[3]=2; L[4]=3;
KScoef(i,j,p,q,L);
==> // ** redefining S
==> // ** redefining u
==> // ** redefining l
==> // ** redefining RC
c=c+imap(RC,C);
c; // it is a coefficient of T1*T2*T3^2 in C[2,9] for x^5+y^14
==> 99/8575
