I would like to have the BUSDAYS function from Financial Toolbox return all weekdays, including those that coincide with NYSE holidays. This is useful when doing analysis for European markets who continue to trade on such holidays.

The default holiday schedule is the NYSE holiday schedule, which is also adopted if the parameter holvec is set to '' (empty string) or [] (empty vector).

If you are only interested in getting all weekdays and ignoring NYSE holidays, you could specify any Saturday or Sunday in your date range as a holiday (i.e., as the value for holvec).

As an example, take the time period 16-05-2011 till 31-05-2011. May 30th is a well-known NYSE holiday: Memorial Day. Calling BUSDAYS without passing a holiday argument results in a vector that excludes May 30th:

vec = datestr(busdays('2011-05-16','2011-05-31'))
 vec =
 16-May-2011
 17-May-2011
 18-May-2011
 19-May-2011
 20-May-2011
 23-May-2011
 24-May-2011
 25-May-2011
 26-May-2011
 27-May-2011
 31-May-2011

On the other hand, specifying the 21st of May (a Saturday) as a holiday gives all weekdays in that time period:

vec = datestr(busdays('2011-05-16','2011-05-31','daily','2011-05-21'))
 vec =
 16-May-2011
 17-May-2011
 18-May-2011
 19-May-2011
 20-May-2011
 23-May-2011
 24-May-2011
 25-May-2011
 26-May-2011
 27-May-2011
 30-May-2011
 31-May-2011
