Introduction

This version of LTPDA is 2.8. This document lists the changes since V2.7.1.

This version requires MATLAB 2011a or above.

Known Issues

On Mac OS X versions which use java 1.7 (on newer versions of MATLAB) there is an issue with the LTPDAprefs GUI when selecting paths of extension modules. There is a bug in the underlying java file-chooser widget which means there is an ‘Open’ button instead of a ‘Choose’ button. The result is that you can’t select a directory but must, instead, select a file (for example the .xml file in the extension) then delete the filename from the path before pressing the + button to add the extension.

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 number of deprecated GUI tools (including the workbench) have been removed from this version. These have been unsupported for a few versions now, and continued maintenance is no longer possible. The user manual, and in particular, the training sessions, have been updated to reflect this. Some of the functionality pertaining to the repository interaction, has been grouped together into a single GUI called LTPDARepositoryQuery.

New Methods

• ao/polyfitSpectrum A new tool which offers an alternative way to fit a smooth model to a spectrum. The method works by fitting a polynomial to the log of the x and y data in the input spectrum.
• timespan/tohtml displays an array of time-span objects in an HTML table.
• New setter methods for AOs: ao/setEnbw, and ao/setNavs.
• There is a new AO built-in model for building pulse-trains (help ao_model_pulsetrain).
• ao/edgedetect is a new method which detects edges in a binary pulse train.
• ao/pad allows padding an AO with a particular value.
• ao/cast allows you to cast the values in an AO to another data type.
• matrix/double returns a matrix of doubles created from the internal objects.
• ao/simplifyZunits simplifies the z-units of the AO.
• ao/simplifyXunits simplifies the z-units of the AO.
• timespan/merge can merge multiple timespans into one.
• ao/detectOutliers detects outliers in a time-series.

Changes to methods

• ao/iplotyy has been rewritten to allow for many new features, including plotting of multiple objects on each of the two axes.
• In all AO constructors, you can now specify a 'timespan' plist key, passing a timespan object which will then be used to split the data before returning.
• Reading from data files with the AO constructor now allows for some header lines to be skipped.
• AO linear fitting methods have improved error estimates.
• pest/jtable displays the values in the parameter estimate object in a table window.
• pest/table displays a pest object at the MATLAB command prompt.
• We have new methods to set the marker face and edge colour on all user objects. We also have a method to set if the marker shouldd be filled or not.
• ao/iplot subplots are now linked when zooming.
• ao/dft now estimates errors based on the frequencies surrounding the target frequency.
