This version of LTPDA is 2.7. This document lists the changes since V2.6.1.

This version requires MATLAB 2010a or above.

Main Changes

This version of LTPDA contains many under-the-hood improvements, particularly in the area of speed, and also some changes to the underlying data structures for analysis objects. In addition, a new test infrastructure is under development which includes a significant number of new unit tests. As a result a large number of bug fixes have been made.

Copying Objects

In order to make deep copies of objects, users should now use the copy() method rather than the old (and confusing) copy constructor. So, instead of

a = ao.randn(10,1)
b = ao(a)

users should now do

b = copy(a)

History context

When tracking processing steps the ‘context’ in which the current command is executed is captured in the history structure. For example, it may capture the name of the script or pipeline being executed. In a later release this may be used to group history steps in the history tree displays.

Function handle objects

Function handle objects have a new property ‘transform’ where you can specify a single or a list of functions that should be applied to the input objects prior to evaluating the function.

New Methods

Changes to methods

LTPDA Repository Interaction

This version of the toolbox has some new utilities for querying LTPDA repositories from within MATLAB.
