60<p>Class definitions for python dispersion model for
61model parameters. These classes are bridges to the C++
62dispersion object.</p>
63<p>The ArrayDispersion class takes in numpy arrays only.</p>
64<p>Usage:
65These classes can be used to set the dispersion model of a SANS model
66parameter:</p>
67<blockquote>
68<div>cyl = CylinderModel()
69cyl.set_dispersion(&#8216;radius&#8217;, GaussianDispersion())</div></blockquote>
70<p>After the dispersion model is set, you can access it&#8217;s
71parameter through the dispersion dictionary:</p>
72<blockquote>
73<div>cyl.dispersion[&#8216;radius&#8217;][&#8216;width&#8217;] = 5.0</div></blockquote>
74<table class="docutils field-list" frame="void" rules="none">

76<col class="field-body" />
77<tbody valign="top">
78<tr class="field"><th class="field-name">TODO:</th><td class="field-body">For backward compatibility, the model parameters are still kept in
79a dictionary. The next iteration of refactoring work should involve moving
80away from value-based parameters to object-based parameter. We want to
81store parameters as objects so that we can unify the &#8216;params&#8217; and &#8216;dispersion&#8217;
82dictionaries into a single dictionary of parameter objects that hold the
83complete information about the parameter (units, limits, dispersion model, etc...).</td>
