Class Demo_Model

Example model. Defines a reflectometry model object for a structure and a a dataset.

model(p) returns f(x;p) corresponding to dataset measured points. model.goodness(p) returns chisq for the given parameters. model.x indicates the measured points model.y, model.dy is the measurement and uncertainty at the points model.rho,model.d are the parameters to the reflectometry model

Instance Methods

__init__(self)
Create a new instance of the demo model

source code

__call__(self, p)
Evaluate the model at parameter vector p, returning f(x;p)
