RE: [pooma-dev] Index Domain Type

[James Crotinger]

Index was never implemented. The notion of Index was a domain with position information. In POOMA r1 you can do the following sort of thing:

  Index I, J;
  A[I][J] = B[J][I];

to assign the transpose of B to A. This does have some uses, but it adds a lot of complexity, so we never put it in.
