Macro Definition Documentation

LUT_constrain

#define LUT_constrain	(		T,
			V,
			W,
			N
	)

Value:

if( V>=T->mx){/*fprintf(stderr, "table overbound:  %g\n", V );*/V=T->mx;}\
  if( V<=T->mn){/*fprintf(stderr, "table underbound: %g\n", V );*/V=T->mn;}

constrain value to table bounds.

If a value lies outside the table, return it to the closest edge. It calls LUT_index().

Parameters

T	pointer to lookup table
V	value to check
W	index of value in its array
N	string for table type

Note

If IMP_FAST is defined, this is ignored

#define LUT_DEV_ONLY

Definition at line 30 of file LUT.h.

LUT_entry

#define LUT_entry	(		A,
			I,
			J
	)		(A)->tab[I][J]

access an entry in the table

Parameters

A	table
I	row
J	column
