names - External interface

Exported names.

In model definition scripts, rather than importing symbols one by one, you can simply perform:

from bumps.names import *

This is bad style for library and applications but convenient for model scripts.

The following symbols are defined:

• np for the numpy array package

• sys for the python sys module

• inf for infinity

• pmath for parameter expressions like 2*pmath.sin(M.theta)

• Parameter for defining parameters

• FreeVariables for defining shared parameters

• Distribution for indicating prior

  probability for a model parameter

• Curve for defining models from functions

• PoissonCurve for modelling data with Poisson uncertainty

• PDF for fitting a probability distribution directly

• FitProblem for defining the fit (see

  BaseFitProblem or MultiFitProblem for details, depending on whether you are fitting a single model or multiple models simultaneously).
