input_truth_table()

MAYAFLUX_API bool MayaFlux::Kinesis::Discrete::input_truth_table ( const std::vector< double > &  inputs, std::span< const double >  coefs  )

noexcept

Any boolean function of the input slots, as a table.

coefs: [threshold, arity, outputs...]. The signal counterpart of truth_table: AND, XOR, majority or any other gate of the slots, missing slots read as zero.
