The data set is available as a MATLAB '.mat' file as well as a Comma-Separated Values (CSV) '.csv' file.

The two data sets are identical except for the way they define dates:

  • The MATLAB file uses MATLAB formatted date values, which can be interpreted using the datestr() function within MATLAB.
  • The CSV file uses UNIX timestamp date values, which can be interpreted as the number of seconds since 00:00 January 1st, 1970 (UTC). Many programming languages support UNIX timestamps natively.

The .mat file can be opened in MATLAB either using the load() function or by 'dragging and dropping' the file into MATLAB's workspace panel.

The .csv file is encoded with Windows linebreaks (i.e. \r\n) and so if you wish to view the raw data within the file it is best to open it in a rich text editor such as Wordpad.

The file can be easily imported into a spreadsheet program such as Excel.
