You are aware of the linear algebra opcodes that I recently contributed to
Csound?

They don't have this kind of range indexing, but that could be added.

I will be adding a manual page for these opcodes soon. In the meantime, you
can look at tests/test24.csd, and the source code (the header of the
Opcodes/linear_algebra.cpp documents it pretty well).

Regards,
Mike
