Welcome to the MfrDB website. The database presented here contains online data of mathematical formulae. All samples are annotated and thus suitable for tuning and testing recognition methods.

The website offers you the possibility to:

  • Find out details about the collected samples.
  • Download the newest release.
  • Find relevant documents and publications.
  • Browse the database online and search by parameters.
