Compatibility issues to older MATLAB versions

Gait-CAD 2014b is not compatible to MATLAB version 2012b and older due to changed graphic commands, e.g. isgraphics.

Posted by Ralf Mikut 2014-12-19

Gait-CAD 2014b is now online

The Gait-CAD version 2014b is now online. The main changes are:

• compatibility to MATLAB 2014b (handling of graphic objects, for some parameters modified
behavior, e.g. for variant 2 in Color/Style selection)
• Association analysis for output variables (integrated functions of Narine Manukyan)
• Self-Organizing Maps (Matlab Neural Networks Toolbox is required)
• integration of Ensemble learning for classification (fitensemble.m; at the moment with fixed parameters:
”Subspace”, 10 learner, ”Discriminant”)
• support for more than one layer in MLPs
• different distant measures for data point distances
• resorting of data point distances using Visual assessment of tendency (VAT) to identify cluster
structures (integrated functions of Timothy Havens, Michigan Tech)
• 2D- and 3D-Poincare-Plots for time series
• extended functionality of Gait-CAD batch files (m-Files, relative directories with project directories
etc.)
• call of macros inside macros
• new option for data import using function importdata.m (relatively fast also for large files, support
for string import)
• new option to fill with NaNs for time series with different lengths
• improved plotting of black-and-white time series with symbols
• tunable marker size for the plotting of single features
• generating and saving archives of feature relevances
• additional plot of regression results in files
• inversion of data point selection
• standard for saving .mat-files now on newest version
• optional deleting of unused terms of output variables
• opening .m-files from Gait-CAD
• plot of existing terms of all output variables in the selected data points (useful for large projects)
• large variety of bug fixes

Gait-CAD 1.8 online

The Gait-CAD version 1.8 is now online, including updated extension packages.

Main changes:
• validation of Hierarchical Bayes classifiers
• test of normal distribution for single features
• further macros to generate single features in the folder ”standardmakros” (MIN, SUM, MEAN)
• loading of Excel files etc. with MATLAB function ”Import Data from File”
• improved visualization of image plot for time series with class sorting
• visualization of regression coefficients for Polynom models with increasing number of features
• conversion of class probabilities (in percentage) into single features
• selection of single features using feature value ranges
• new m-file generate_new_gaitcad_project.m to save Gait-CAD projects with variables from MATLAB
workspace
• selecting of additional search paths for plugins or m-files (temporary or permanent)
• repair of empty names for single features, time series, output variables and linguistic terms (to
avoid problems especially in the selection durinbg macro execution)
• improved MATLAB version compatibility (MATLAB 2013a)
• large variety of bug fixes... read more
