/* ---------- mtx_*~ - signal matrix multiplication object with message matrix-coeff. ----------- */
/* usage:
* [mtx_*~ <#out> <#in>]: multiply #in signals with a <#out,#in>-matrix to get #out-signals
* [mtx_*~ <#io>]: multiply #io signals with a <#io,#io>-matrix to get #io-signals
*
* 1st inlet: (message only): the matrix to multiply with (defaults to zero(#out, #in)
* 2nd-(n-1)th inlet: the input signals
* last inlet: the interpolation time in [ms]
*
* this also implements a compatibility layer with old objects from tm and jmz
* that provide basically the same functionality
*
* further note:
* pd does not like signal-objects that don't listen to signals on the very first inlet
* however, the first signal-inlet of [mtx_*~] is the 2nd(!) inlet
* to achieve this, we silently ignore any signal that comes in at the first inlet
