freev()

subroutine freev	(	integer	n,
		integer	nfree,
		integer, dimension(n)	index,
		integer	nenter,
		integer	ileave,
		integer, dimension(n)	indx2,
		integer, dimension(n)	iwhere,
		logical	wrk,
		logical	updatd,
		logical	cnstnd,
		integer	iprint,
		integer	iter
	)

This subroutine counts the entering and leaving variables when iter > 0, and finds the index set of free and active variables at the GCP.

Parameters

n	number of parameters
nfree	number of free parameters, i.e., those not at their bounds
index	for i=1,...,nfree, index(i) are the indices of free variables for i=nfree+1,...,n, index(i) are the indices of bound variables On entry after the first iteration, index gives the free variables at the previous iteration. On exit it gives the free variables based on the determination in cauchy using the array iwhere.
nenter	TODO
ileave	TODO
indx2	On entry indx2 is unspecified. On exit with iter>0, indx2 indicates which variables have changed status since the previous iteration. For i= 1,...,nenter, indx2(i) have changed from bound to free. For i= ileave+1,...,n, indx2(i) have changed from free to bound.
iwhere	TODO
wrk	TODO
updatd	TODO
cnstnd	indicating whether bounds are present
iprint	control screen output
iter	TODO
