You cannot define fractional indices in any software.......fortran, c takes from 0 to n...where as matlab takes from 1 to n. May be you want to call a fractional array; you have to follow like this.
x = rand(10,1) ;
n = length(x) ;
for i = 1:n
x(i)
end

'have to' for what purpose?
Use
doc containers.Map
if you want to set up a finite lookup table of results to index into without using integer lookups.
But if your code is sufficiently fast then a function works fine and recalculate whatever is asked for.
