generate_larnv_seed()

integer function, dimension(4), public dbm_tests::generate_larnv_seed	(	integer, intent(in)	irow,
		integer, intent(in)	nrow,
		integer, intent(in)	icol,
		integer, intent(in)	ncol,
		integer, intent(in)	ival
	)

Generate a seed respecting the lapack constraints,.

• values between 0..4095 (2**12-1)
• iseed(4) odd also try to avoid iseed that are zero. Have but with a unique 2D mapping (irow,icol), and a 'mini-seed' ival

Parameters

irow	1..nrow
nrow	...
icol	1..ncol
ncol	...
ival	mini-seed

Returns

a lapack compatible seed
