Features: Completely GUI based. All functions can be accessed via a convenient graphical user interface. But don't worry: All these functions are still available at the Matlab™ command line. More features

Just a first impression of what the whole thing looks like…

Got interested? Want to see more? Take a look at the GUI and it's subwindows.


A rather incomprehensive list…

  • Completely GUI based
  • All functions accessible via CLI
  • Modular design
  • Load diverse data formats1)
  • Display modes: 2D and 1D (x, y)
  • Highly configurable display options
  • Preprocessing (combine, accumulate)
  • Measuring points and distances
  • Averaging (with error bars)
  • Analysis of MFEs
  • Info GUI for datasets2)
  • Fitting arbitrary functions (1D)
  • Integrated help
  • Exporting data
  • Exporting display3)
  • >100 Bugs (mostly unidentified)


Apologies, currently there is no stable release available. See the development page for more details.

If you're still interested in downloading: ZIP archive of the current developer's version. Please note: You've been warned that it will contain many bugs.

Latest development release: v.0.0.38 (2015-11-03).

Please note: Run the installer after you updated to a new version to update your configuration. You will not loose your personal settings. Take care that it can write path and config files.

System requirements

  • Matlab 2012a (7.14) or newer (only tested with 2010a and newer)
  • Minimum screen dimensions of 1280×800 px

<note warning>Please note: Currently, using Matlab 2014b is highly discouraged, due to MathWorks having changed completely the graphics subsystem. I'm currently working on improving the situation, but cannot promise any success soon.</note>
