D.12.7.7 tracemult

Procedure from library rootsmr.lib (see rootsmr_lib).

Usage:
tracemult(f,B,I);f poly, B,I ideal

Return:
number: the trace of the multiplication by f (m_f) on r/I, written in the monomial basis B of r/I, r = basering (faster than matmult + trace)

Assume:
I is given by a Groebner basis and B is an ordered monomial basis of r/I

Example:
 
See also: matmult; trace.
