void vil_exp_grad_filter_1d	(	const srcT *	src,
		vcl_ptrdiff_t	sstep,
		destT *	dest,
		vcl_ptrdiff_t	dstep,
		int	n,
		accumT	k
	)		[inline]

Apply exponential gradient filter to 1D data. Form: sign(i)*exp(c*|i|).

Apply filter to n values src[i*sstep] to produce output dest[i*dstep] Exponential gradient filter of the form sign(i)*exp(c*|i|) applied. c=log(k) Uses fast recursive implementation.
