Example Inputs

The first column represents the name of the parameters. The second column specifies whether the parameters are optional or not. Finally the last column provides some sample input data.
Function call input string-keys are always in the format : "NAME.EXTTAG.TICKER" The "EXTTAG.TICKER" part is determined from the output of other, capetools, object creation functions.


ArgNameIsOptional (Excel only)Example
CalendarKeyFALSECalendarKeyNAME.EXTTAG.TICKER (from a function call)
DatesFALSEAreBusinessDates_Dates_Range (creates a range object)


Example range for parameter : Dates

Within Excel, a range such as this can be passed directly into the Dates parameter.


Data is stored within the second column (Vector of data)..

Example C# API usage for setting the range data for parameter : Dates 


CTQL.CTRangeData AreBusinessDates_Dates;


int[] arrBAreBusinessDates_Dates = {
CTQL.Date.serialNumber("1/2/2006", "dd/mm/yyyy"),
CTQL.Date.serialNumber("15/2/2006", "dd/mm/yyyy"),
CTQL.Date.serialNumber("16/2/2006", "dd/mm/yyyy"),
CTQL.Date.serialNumber("17/2/2006", "dd/mm/yyyy"),
CTQL.Date.serialNumber("2/2/2006", "dd/mm/yyyy"),
CTQL.Date.serialNumber("3/2/2006", "dd/mm/yyyy"),
CTQL.Date.serialNumber("4/2/2006", "dd/mm/yyyy"),
CTQL.Date.serialNumber("5/2/2006", "dd/mm/yyyy"),
CTQL.Date.serialNumber("6/2/2006", "dd/mm/yyyy")  //  Array Data

};

CTQL.IntVector arrAreBusinessDates_Dates =
new  CTQL.IntVector(arrBAreBusinessDates_Dates);

// Second parameter determines whether the array is a column array (false) or a row array (true)
AreBusinessDates_Dates = new  CTQL.CTRangeData(arrAreBusinessDates_Dates, false);


Example function usage

The VB.NET, J#, C++.NET, Java, Excel VBA, Visual Basic 6 (via COM) and C++ examples below contain function code stubs for the calls leading up to this function call. However, the function call for this function is displayed.
You can easily reproduce the stub functions code from the C# example.


If you are accessing this functrion via the MiniXL libraries, this function is present within the CT.QL.Curves20 MiniXL Excel Addin.

Within our Excel Example Addin Generator, we have used the following QuantTools sub-functions in order to prepare the arguments needed to call the AreBusinessDates() function. If you are executing this function via the MiniXL libraries, the module addin name, (in brackets, to the right of the sub-functions listed below), indicates the MiniXL library in which the sub-function is held. You will need to load this library into your Excel session (along with any other libraries that the sub-function call within the addin requires (ie - CT.QT.Utils20 addin in almost all cases) in order for the example to compute successfully.

These are the financial QuantTools sub-function calls that are used within the examples :
