Mesh Array of double boost

[leeto]

I wanna create mesh Array using boost elements, that will be do the same that code below, but can accept numbers of double.
Please advice me any boost array that give me needed functionality. It will be great that advised element has the same argument list. I mean
// [base,stride,bound)
// [0,2,4)
P.S. Or may be there are any opportunity modify this boost::multi_array_types::index_range in order do make it accept double...
Many thanks in advance!
