RegularChains[MatrixTools]
JacobianMatrix
Jacobian matrix of a polynomial system modulo a regular chain
Calling Sequence
Parameters
Description
Examples
JacobianMatrix(sys, rc, R)
sys
-
system of polynomials in R
rc
strongly normalized regular chain
R
polynomial ring
The command JacobianMatrix(sys, rc, R) returns the Jacobian matrix of sys modulo the saturated ideal of rc.
This command is part of the RegularChains[MatrixTools] package, so it can be used in the form JacobianMatrix(..) only after executing the command with(RegularChains[MatrixTools]). However, it can always be accessed through the long form of the command by using RegularChains[MatrixTools][JacobianMatrix](..).
