Рабочий процесс для Создания и Анализа ratecurve и parametercurve

Рабочий процесс для создания и анализа `ratecurve` и `parametercurve`

Используйте ratecurve или irbootstrap создать ratecurve объект.

% Create a ratecurve
Settle = datetime(2019,9,15);
Type = "zero";
ZeroTimes = [calmonths(6) calyears([1 2 3 4 5 7 10 20 30])]';

ZeroDates = Settle + ZeroTimes;
myRC = ratecurve('zero',Settle,ZeroDates,ZeroRates)

myRC = 

  ratecurve with properties:

                 Type: "zero"
          Compounding: -1
                Basis: 0
                Dates: [10×1 datetime]
                Rates: [10×1 double]

Используйте zerorates, forwardrates, или discountfactors с ratecurve объект.

Преобразуйте `RateSpec` к `ratecurve` Объект

Можно создать RateSpec использование intenvset или toRateSpec от IRDataCurve объект. Затем вы можете тайный этот ранее созданный RateSpec к ratecurve объект.

% Assume there is a RateSpec
Settle = datetime('01-Oct-2019');
ZeroTimes = [calmonths(6) calyears([1 2 3 4 5 7 10 20 30])]';
ZeroRates = [0.0052 0.0055 0.0061 0.0073 0.0094 0.0119 0.0168 0.0222 0.0293 0.0307]';
ZeroDates = Settle + ZeroTimes;
Basis = 1;
RateSpec = intenvset('StartDates', Settle, 'EndDates', ZeroDates, ...
    'Rates', ZeroRates, 'Basis', Basis)

RateSpec = 

  struct with fields:

           FinObj: 'RateSpec'
      Compounding: 2
             Disc: [10×1 double]
            Rates: [10×1 double]
         EndTimes: [10×1 double]
       StartTimes: [10×1 double]
         EndDates: [10×1 double]
       StartDates: 737699
    ValuationDate: 737699
            Basis: 1
     EndMonthRule: 1

% Convert the RateSpec to a ratecurve
myRC = ratecurve("zero",RateSpec.ValuationDate,RateSpec.EndDates,RateSpec.Rates,...
"Compounding",RateSpec.Compounding,"Basis",RateSpec.Basis)

myRC = 

  ratecurve with properties:

                 Type: "zero"
          Compounding: 2
                Basis: 1
                Dates: [10×1 datetime]
                Rates: [10×1 double]
               Settle: 01-Oct-2019
         InterpMethod: "linear"
    ShortExtrapMethod: "next"
     LongExtrapMethod: "previous"

% Check the discount factors
OldDF = intenvget(intenvset(RateSpec,'EndDates',datetime('01-Oct-2024')),'Disc')
NewDF = discountfactors(myRC,datetime('01-Oct-2024'))

OldDF =

    0.9424

NewDF =

    0.9424

В этом случае, RateSpec и ratecurve идентичны. Это не может всегда иметь место потому что yearfrac использованные для расчета времена в ratecurve в то время как date2time используется в вычислении RateSpec. Для получения дополнительной информации смотрите Различие Между yearfrac и date2time (Financial Toolbox).
