Variables and Parameter Names

Conventions for Parameters

  1. Do not use capitalization to indicate whether a value in the status dictionary is variable.
  2. Where available, use the notation from P.Dayan & L.F.Abbott, Theoretical Neuroscience, MIT Press, 2001.
  3. Where not available, use a notation that is consistent with Dayan & Abbott.
  4. Subscripts are indicated by underscores
