Maxima Function
niceindices (expr)
Renames the indices of sums and products in expr.
niceindices
attempts to rename each index to the value of niceindicespref[1]
,
unless that name appears in the summand or multiplicand,
in which case niceindices
tries
the succeeding elements of niceindicespref
in turn, until an unused variable is found.
If the entire list is exhausted,
additional indices are constructed by appending integers to the value of
niceindicespref[1]
, e.g., i0
, i1
, i2
, ....
niceindices
returns an expression.
niceindices
evaluates its argument.
