Note also that one of the two matrix multiplicators for signals is backwards (OTOH, from the perspective of its author, all other matrix multiplicators for pd are backwards...). This just means that one kind of object makes rows of the grid correspond to inputs, while the other makes columns of the grid correspond to inputs.
for clarification: [matrix~] (from zexy<2.0) will get a vector of output-signals O^ from a vector of input signals I^ via the following equation: O^'=I^'*A this is a bit weird since in the scientific community this equation is usually denoted as: O^=B*I^ (both equations are the same if B==A')
however it does makes some sense (at least: it did for me :-)) in terms of the pd-patch (creation arguments of [matrix~] and how you connect cords to the inputs of the object)
anyhow: [matrix~] is deprecated, don't use it! use [mtx_*~] instead, which follows the scientific convention... the help-patches in the CVS are updated (one of the greatest drawbacks of [matrix~] was, that it had non-standard behaviour and there was NO help-patch at all....)
