Exponential values

exp is not recommended. Use timetable instead. For more information, see Convert Financial Time Series Objects fints to Timetables.

Description

example

newfts = exp(tsobj) calculates the natural exponential (base e) of all the data in the data series of the financial time series object tsobj and returns the result in the object newfts.

Examples

  1. Create a fints object.

    dates_and_times = (now:now+5)'
    dates_and_times =
    
       1.0e+05 *
    
        7.3840
        7.3840
        7.3840
        7.3841
        7.3841
        7.3841
    
     tsobj = fints(dates_and_times, randn(6,1))
    Warning: FINTS is not recommended. Use TIMETABLE instead. For more information, see Convert Financial Time Series Objects (fints) to Timetables.

        {'12-Sep-2021'}    {'12:30'      }    {[      -1.3077]}
  2. Calculate exponential values using exp.

    newfts = exp(tsobj)
