f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	44 AOs can be constructed in many different ways. Each of the different ways is
f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	45 called a constructor. For example, there is a constructor to make an AO from
f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	46 a set of numeric values, there is also a constructor to make an AO from a data file.
f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	47 Each time you construct an AO, you make an instance of the class, <tt>ao</tt>. The variable
f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	48 you have in MATLAB is then just a reference to the object you constructed.

f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	104 In addition to the standard MATLAB scripting interface, LTPDA offers a

f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	106 processing pipelines by dragging and dropping blocks on to a canvas, then
f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	107 joining up the blocks.

f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	110 This graphical programming environment is called an LTPDA Workbench. To start

f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	123 The use of the LTPDA workbench is quite intuitive, so hopefully playing around is sufficient.

f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	130 Then you can drag an AO constructor block from the
