SliToMathematicaIndex


Name:
SliToMathematicaIndex - Convert SLI indices to Mathematica-like indices
Synopsis:
sliIndex MathematicaToSliIndex -> mathematicaIndex  

Examples:
 
3 SliToMathematicaIndex -> 4
[ 3 1 ] SliToMathematicaIndex -> [ 4 2 ]


Description:
 
"SliToMathematicaIndex" converts SLI indices to Mathematica-like
indices.
For an array of size N, valid SLI indices are in the range 0..N-1 while
valid Matematica indices are in the range -N..-1, 1..N (negative
indices indicating backward indexing from the end of the array).

Note that this routine will always return positive indices.

Remarks:
 
Note the difference in the argument list compared to
"MathematicaToSliIndex". Only one argument, the index(array)
itself, is needed.

The implementation is _most_ simple (add 1 to the index), but the
Routine is supplied for symmetry reasons.

Note that this routine will always return positive indices. Hence,
the sequence
[array] MathematicaToSliIndex SliToMathematicaIndex
is NOT identity.
