NPef - Estimate Non-stationary PEF in N dimensions

Pef < data.H a= center=1 gap=0 [maskin=] [maskout=] > pef.H

Estimates PEF by least squares, using helix convolution. Can ignore missing data

from history	integer array	n	reads n1 , n2 , n3 , etc.
from par	integer	niter =100	number of iterations
	real	epsilon =0.01	regularization parameter
	integer array	a =	filter size
	integer array	center =1	zero-lag position (filter centering)
	integer array	gap =0	filter gap
	filename	maskin, maskout (optional)	data selectors
to history	integer array	lag	comma separated list of filter lags
