This version of LTPDA is 2.9.4. This document lists the changes since V2.8.

This version requires MATLAB 2012b or above.

Known Issues


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.

This version also includes changes to the plotting tools to adapt to the changes to the graphics objects in recent MATLAB versions.

It is now possible to submit and retrieve MATLAB figures to/from an LTPDA repository, assuming the figures are created using LTPDA plotting tools (like iplot, ao/plot).

Spectral estimation methods now automatically drop the first N samples (defined by the window function) from the resulting estimates as these samples are biased. This can be deactivated in the plist. See help ao/psd for example.

LTPDA now supports data types other than double() in AOs, and some methods properly treat these data types.


A number of changes made required us to change the minimum MATLAB installation requirements to

Software Version
MATLAB 8.0 (R2012b)
Signal Processing Toolbox 6.18
Symbolic Math Toolbox 5.9
Optimisation Toolbox* 6.2.1
