prn1lb()

subroutine prn1lb	(	integer	n,
		integer	m,
		double precision, dimension(n)	l,
		double precision, dimension(n)	u,
		double precision, dimension(n)	x,
		integer	iprint,
		integer	itfile,
		double precision	epsmch
	)

This subroutine prints the input data, initial point, upper and lower bounds of each variable, machine precision, as well as the headings of the output.

Parameters

n	On entry n is the number of variables. On exit n is unchanged.
m	On entry m is the maximum number of variable metric corrections allowed in the limited memory matrix. On exit m is unchanged.
l	On entry l is the lower bound of x. On exit l is unchanged.
u	On entry u is the upper bound of x. On exit u is unchanged.
x	On entry x is an approximation to the solution. On exit x is the current approximation.
iprint	It controls the frequency and type of output generated: iprint<0 no output is generated; iprint=0 print only one line at the last iteration; 0<iprint<99 print also f and |proj g| every iprint iterations; iprint=99 print details of every iteration except n-vectors; iprint=100 print also the changes of active set and final x; iprint>100 print details of every iteration including x and g; When iprint > 0, the file iterate.dat will be created to summarize the iteration.
itfile	unit number of iterate.dat file
epsmch	machine precision epsilon
