New Features

R2014a (Version 9.0)

Released: 6 Mar 2014

Version 9.0, part of Release 2014a, includes the following enhancements:

  • Repeated measures modeling for data with multiple measurements per subject
  • fitcsvm function for enhanced performance of support vector machines (SVMs) for binary classification
  • evalclusters methods to expand the number of clusters and number of gap criterion simulations
  • p-value output from the multcompare function
  • mnrfit, lassoglm, and fitglm functions accept categorical variables as responses
  • Functions accept table inputs as an alternative to dataset array inputs
  • Functions and model properties return a table rather than a dataset array

See the Release Notes for details.
