Hi, is it possible to apply matrix operations on certain parts of data tables using table functions?

We have some complex matrix functions, already implemented in C# and tested, for financial forecasts and estimations. These matrix functions must be applied on selected parts of huge data tables. For example, separate forecasts for product A, product B, and so on, with data of all products in a single table. The question is, can we use finaquant's table functions to feed these subtables into our matrix functions? Is there an example for this complicated task?

Thanks, Chrishna
