Function/Subroutine Documentation

subroutine bud_lsm_csr::fold_col_only	(	class(lsm_csr), intent(in)	from,
		integer(il_), intent(in)	nc,
		class(lsm_csr), intent(inout)	to,
		logical, intent(in), optional	single
	)

Parameters

[in]	from	the originating sparse pattern
[in]	nc	new number of columns in the sparse pattern
[in,out]	to	the resulting sparse pattern
[in]	single	optional=.false. if .true.: will compress equivalent entries to a single entry, no double entries will be found subsequently.

TODO check that the last row has > 0 elements this will justify the -1 below
