Gary,
there is not any other language behind. Some logic rules like
1.
AND truth table is equivalent to the multiplication of binary
quantities.
1*0=0*1=0*0=0
1*1=1
2.
For a binary COND
IIF(COND,A,B) is equivalent to COND*A+(NOT(COND))*B
There is no reason to step into vector spaces, it will not be that
simple anymore, we should use linear independence [and it is not
always obvious...]
Dimitris Tsokakis
PS.I am not a programmer, I have not the slightest idea of any
programming language, just some AFL to do the job, nothing more.

but my friend always points out that vector math is much faster than
looping as I'm sure your code will demonstrate.
