f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	41 The use of LTPDA objects requires some understanding of the nature of objects as implemented in MATLAB.

f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	65 Each class in LTPDA has a set of methods (functions) which can operate/act on instances of the class (objects).
f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	66 For example, the AO class has a method <tt>psd</tt> which can compute the Power Spectral Density estimate of a
f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	67 time-series AO.

f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	70 To see which methods a particular class has, use the <tt>methods</tt> command. For example,

f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	76 To call a method on an object, <tt>obj.method</tt>, or, <tt>method(obj)</tt>. For example,

f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	84 Additional arguments can be passed to the method (a <tt>plist</tt>, for example), as follows:
f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	85 <div class="fragment"><pre>
f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	86 >> b = a.psd(pl)

f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	168 All object properties must be set using the appropriate setter method. For example, to set the name of a IIR filter

f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	189 Since all objects in LTPDA are handle objects, creating copies of objects needs to be done differently than in standard
f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	190 MATLAB. For example,
f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	191 <div class="fragment"><pre>

f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	195 in this case, the variable <tt>b</tt> is a copy of the handle <tt>a</tt>, not a copy of the object pointed too
f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	196 by the handle <tt>a</tt>. To see how this behaves,

f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	209 Copying the object can be achieved using the copy constructor:
