dd_triangle

Triangle distribution

Syntax

info = dd_triangle()
P = dd_triangle(r,param)
Parameters
  • r - Distance axis (N-array)
  • param - Model parameters
Returns
  • P - Distance distribution (N-array)
  • info - Model information (struct)

Model

This provides a simple triangular distribution.

Variable Symbol Default Lower bound Upper bound Description
param(1) r_0 3.5 1.0 20 mode
param(2) w_\mathrm{L} 0.3 0.1 5 left width
param(3) w_\mathrm{R} 0.3 0.1 5 right width

Example using default parameters:

Description

info = dd_triangle()

Returns an info structure containing the specifics of the model:

  • info.model - Full name of the parametric model.
  • info.nparam - Total number of adjustable parameters.
  • info.parameters - Structure array with information on individual parameters.
P = dd_triangle(r,param)

Computes the distance distribution model P from the axis r according to the parameters array param. The required parameters can also be found in the info structure.
