Module demo_chisq_surfaces

Pure numeric python implementation of Parratt's recursion for computing reflectivity as a function of Q and lambda.

Classes
	Chisq Compute chisq(p) given f(p),y,dy
	Demo_Model Example model.

Functions

theory(Q, d, rho)
Compute reflectometry theory from using parratt formalism

source code

sampledata(Q, d, rho)
Generate sample data given the model Q,d,rho

source code

build_landscape(fn, x, y, dim=(50,50))
Construct a 2D landscape for the function f((x,y)) over x=[lo, hi], y=[lo,hi] with the number of steps dim=(nx,ny) defaulting to 50x50

source code

plot_mesh(x, y, Z)
