D.6.16.3 KSlinear

Procedure from library kskernel.lib (see kskernel_lib).

Usage:
KSlinear(matrix M);
computes matrix of linear terms of the kernel of the
Kodaira-Spencer map. To be called after the procedure
KSker(p,q)

Return:
nothing; but replaces elements of the matrix KSkernel in the ring Ksring with their leading monomials
w.r.t. the local ordering (ls)

Example:
 
LIB "kskernel.lib";
int p=6;
int q=7;
KSker(p,q);
setring Kskernel::KSring;
KSlinear(KSkernel);
print(KSkernel);
==> 0,     0,     0,     0,     0,      2*T(1), 
==> 0,     0,     0,     0,     0,      3*T(2), 
==> 0,     0,     0,     0,     0,      4*T(3), 
==> 0,     0,     0,     2*T(1),3*T(2), 9*T(4), 
==> 0,     0,     0,     3*T(2),4*T(3), 10*T(5),
==> 2*T(1),3*T(2),4*T(3),9*T(4),10*T(5),16*T(6)
