This toolbox implements some generic functions used by other toolboxes. Originally it was spun out of the IVM 0.221 toolbox.
Version 0.163
-------------
Added plotMatrix for visualizing matrices on figure axes.
Version 0.162
-------------
Added files for printing to latex plots from Octave.
Version 0.161
-------------
Antti updated lnDiffErfs. Added readBinaryDoubles and printPlot.
Version 0.16
------------
Release for ICML tutorial. Added cumGamma and gammaPdf. Also added isoctave and several matlab helper files for reading from file IDs.
Version 0.159
-------------
Minor release for dimensional reduction demos. Added centeringMatrix.m.
Version 0.158
-------------
Antti Honkela provided the files lnDiffErfs and gradLnDiffErfs to assist in computing the DISIM kernel from the kernel toolbox stably.
Version 0.157
-------------
Added treeFindLeaves.
Version 0.156
-------------
Moved treeFindParents, treeFindChildren and treeSwapNode into this toolbox from MOCAP toolbox.
Version 0.155
-------------
Moved lnCumGaussSum from NCNM toolbox to this toolbox as part of merge of NCNM toolbox into NOISE and IVM toolboxes.
Version 0.154
-------------
Added code for checking Hessian matrices.
Version 0.153
-------------
Added comments to files and changed jitChol, pdinv and logdet so that
they can return any jitter added. If the return the jitter then they don't emit a warning.
Version 0.152
-------------
There was a sign error in lnDiffCumGaussian. This has been fixed. The sign error was replicated in the NOISE and PRIOR toolboxes (a case of two wrongs making a 'right'). This means that earlier versions of this toolbox are incompatible with versions of PRIOR before 0.131 and versions of NOISE before 0.131.
Version 0.151
-------------
Sped up the sparseDiag command using spdiag, this makes the FGPLVM code run much faster.
Version 0.15
------------
Fixed inconsistencies in logdet and pdinv and corrected the amount of jitter that is added at first try. Placed the jitter addition in a new file jitChol which is called by both functions.
Added kldivGaussian for computing Gaussian Kullback-Leibler divergences.
Added deg2rad for converting degrees to radians.
Version 0.142
-------------
Added sparseDiag and moved data loading methods into the new DATASETS toolbox.
Version 0.14
------------
Moved in lvmLoadData and mappingLoadData as generic methods of loading in data sets.
Version 0.131 Release Notes
---------------------------
Added files getline.m and tokenise.m which are string utilities for reading and processing files.
Version 0.13 Release Notes
--------------------------
pdinv now adds jitter which is proportional to the mean of the diagonal elements of the matrix.
