[PD] matrix operations with audio signals

Dear list,

I have been creating 2D and 3D oscilloscope graphics with audio signals 
in Pure Data for some time now. I've started digging deeper into 3D math 
and have found that the ability to do matrix operations at audio rate 
would be extremely useful.

Right now, the only option I can see is to use [matrix~] from IEMmatrix 
lib, and to pack my other audio vectors using [mtx_pack~] in a subpatch 
with [block~ 1] to get samplewise operations.

Is this the best/only way to do this? Seems like the [block~] could make 
it unnecessarily expensive.
