    I would like to use the Frequency Domain System Identification Toolbox with the following conditions.
    • I request it for my personal use, in my teaching or in my scientific study,
    • when I use it for work to be published, I refer to it with proper data,
    • I may not put any portion of the toolbox on a WEB page,
    • if colleagues are interested, I will advise them to request their own copy through this page, rather than passing my copy to them.

  • download the zip file of the toolbox, and
  • make the necessary settings in MATLAB (the toolbox was tested for MATLAB 2019a and earlier versions):
    • make sure no old version of the toolbox is on your path ('which fdtool' should show no file in MATLAB),
    • unzip the files somewhere - the directory structure should be something like
        ... fdident\fdident
          ... fdident\fdident\private
          ... fdident\fdident\@fiddata
          ... fdident\fdident\@fidmodel
          ... fdident\fdident\@iddat
          ... fdident\fdident\@tiddata
        ... fdident\fddemos
    • add to the path the directories ...\fdident\fdident and ...\fdident\fddemos (e.g. in MATLAB:
      where DIR is the access of the directory,
    • type fdtool in MATLAB
