source: cpp/frams/neuro/impl/neuroimpl-simple.h @ 726

Last change on this file since 726 was 726, checked in by Maciej Komosinski, 6 years ago
  • Changed Model::singleStepBuild() to Model::addFromString() to create model elements; the latter requires explicit indication of element type (P/J/N/C)
  • Removed old compatibility source (#ifdef MODEL_V1_COMPATIBLE) from f1->f0 converter and neuron definitions
  • Property svn:eol-style set to native
