| Description: |
For each element of the input array, MapIndexed calls f with
two arguments, the current index and the element. It replaces
the element with the result of f.
MapIndexed works similar to Map, however, in adition to the
element its index within the array is also passed to the function.
Note that the index starts with 1, according to Mathematica convention.
This is unlike in forallindexed where in accordance with Postscript
array indices start with 0.
The result of MapIndexed is a list with the same number of values as the
argument list.
If f does not return a value, MapIndexed fails.
If f returns more than one value, the result of MapIndexed is
undefined.
Alternatives: Function MapIndexed_a for lists and MapIndexed_s
for strings (both undocumented) -> behaviour and synopsis are
the same.
