nhelicon - non stationary convolution
Initializer - call nhelicon_init(aa)
Operator - ierr=nhelicon_lop(adj,add,xx,yy)
type(nfilter)
nhelix filter to perform convolution with
standard operators parameters
Nonstationary convolution, inverse to deconvolution. Requires the filter be causal with an implicit "1." at the onset.
