regularSequenceCheck -- how much of a list is regular

Synopsis

Description

Given a list X, the function regularSequenceCheck gives an integer indicating how many initial elements of a List form a regular sequence.
i1 : A = ZZ[x_1..x_4]/(x_4^2)	  

o1 = A

o1 : QuotientRing
i2 : regularSequenceCheck({x_1..x_4},A)	    

o2 = 3

This symbol is provided by the package Depth.

Caveat

regularSequenceCheck merely checks the injectivity of the maps in question. It does not check to see if XA = A.

For the programmer

The object regularSequenceCheck is a method function.
