Syntax

outRates = zerorates(obj,inpDates)
outRates = zerorates(___,inpComp,inpBasis)

Description

example

outRates = zerorates(obj,inpDates) computes zero rates for the ratecurve object (obj) based on inpDates.

example

outRates = zerorates(___,inpComp,inpBasis) optionally specifies the input compounding frequency (inpComp) and the input day-count basis (inpBasis) in addition to any of the input argument combinations in the previous syntax.

Create a ratecurve object using ratecurve. 

Settle = datetime(2019,9,15);
Type = 'zero';
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;
 
myRC = ratecurve('zero',Settle,ZeroDates,ZeroRates,'Compounding',2,'Basis',5,'InterpMethod',"pchip",'ShortExtrapMethod',"linear",'LongExtrapMethod',"pchip")
myRC = 
  ratecurve with properties:

                 Type: "zero"
          Compounding: 2
                Basis: 5
                Dates: [10x1 datetime]
                Rates: [10x1 double]
               Settle: 15-Sep-2019
         InterpMethod: "pchip"
    ShortExtrapMethod: "linear"
     LongExtrapMethod: "pchip"

Compute the zero rates using zerorates.

CurveSettle = datetime(2019,9,15);
outRates = zerorates(myRC,CurveSettle+30:30:CurveSettle+720)
outRates = 1×24
