**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.
