Syntax

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

Description

example

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

example

outRates = zerorates(___,inpComp,inpBasis) specifies options in addition to any of the input argument combinations in the previous syntax.

Create a parametercurve object using parametercurve. 

PCobj = parametercurve('zero',datetime(2019,9,15),@(t)polyval([-0.0001 0.003 0.02],t),'Compounding',4,'Basis',5,'Parameters',[-0.0001 0.003 0.02])
PCobj = 
  parametercurve with properties:

              Type: "zero"
            Settle: 15-Sep-2019
       Compounding: 4
             Basis: 5
    FunctionHandle: @(t)polyval([-0.0001,0.003,0.02],t)
        Parameters: [-1.0000e-04 0.0030 0.0200]

Compute the zero rates using zerorates.

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

Input Arguments

collapse all

parametercurve object, specified as a previously created parametercurve object.

Data Types: object

Input dates, specified as a scalar or an NPOINTS-by-1 vector of a datetimes, serial date numbers, cell array of date character vectors, or string array. StartDates must be earlier than EndDates.

Data Types: string | datetime | double | char | cell

(Optional) Input compounding frequency, specified as a scalar numeric using one of the supported values: –1, 0, 1, 2, 3, 4, 6, or 12.

Data Types: double

(Optional) Input day-count basis, specified as a scalar integer.
