RegularChains[MatrixTools][JacobianMatrix] - Jacobian matrix of a polynomial system modulo a regular chain
|
Calling Sequence
|
|
JacobianMatrix(sys, rc, R)
|
|
Parameters
|
|
sys
|
-
|
system of polynomials in R
|
rc
|
-
|
strongly normalized regular chain
|
R
|
-
|
polynomial ring
|
|

Description
|
|
•
|
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](..).
