Phase-Design, Deprecated
Updated Feb 7, 2011 by Per.Andreas.Brodtkorb@gmail.com

Introduction

The WAFO version 2.5 release includes many new functions and refactorings of old functions. Many functions are now distributed under the GNU LESSER GENERAL PUBLIC LICENSE.

The details are given below:

Details

Refactorings

  • XXXpdf, XXXcdf, XXXrnd, XXXinv, XXXfit, XXXplot renamed to pdfXXX, cdfXXX, rndXXX, invXXX fitXXX, plotXXX, respectively.
  • XXXstat renamed to momXXX
  • fitXXX now returns a structure instead of a vector.
  • All pdfXXX, cdfXXX, invXXX, momXXX now accepts a structure as returned from fitXXX functions.
  • All momXXX functions return mean, std, skewness and kurtosis.
  • iqr renamed to iqrange
  • identify renamed to clickslct
  • whisto renamed to histgrm
  • mle renamed to mlest
  • empdistr renamed to plotedf
