    You can already do Total(A1) to sum an array.
     
    For dot product, I have been thinking something more generic could work even better  (not implemented):
    MapData(A1, $val * A2[$i]) - basically, besides exposing $val, also expose the index $i. Just an idea for now.

    There are some more suggestions:
    More linear and bi-linear interpolation support, polynomial calculation using arrays as coefficients.

    The same has been also requested for any attributes used by an analysis that get their PI point name from a table. Currently, the attribute gets resolved only during analysis startup. Changes to the underlying table require the service restart.

    Would you please expand on this idea little bit? Do you mean something like custom/predefined Expression functions, or rather full programmatic access?
