names - External interface

Exported names.

Usage:

import bumps.names as bp … bp.FitProblem(experiment)

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

Math functions:

• math constants: inf, pi, e

• exponentials: exp, log, log10, sqrt

• degrees, radians

• radians trig: sin, cos, tan, arcsin, arccos, arctan, arctan2

• degrees trig: sind, cosd, tand, arcsind, arccosd, arctand, arctan2d

• hyperbolic trig: sinh, cosh, tanh, arcsinh, arccosh, arctanh

• pmath for pmath.min() and pmath.max()

Problem definition functions:

• 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.

Jupyter notebook functions:

• Simple fitter: bumps.fitters.fit(), bumps.fitters.plot_convergence()

• Webview server: bumps.webview.server.webserver.start_bumps, bumps.webview.server.webserver.display_bumps

• MCMC save/load: bumps.fitters.load_session(), bumps.fitters.load_fit_from_session(), bumps.fitters.load_fit_from_export()
