Zero curve bootstrapping from coupon bond data given yield

`[ZeroRates, CurveDates] = zbtyield(Bonds, Yields, Settle,`

OutputCompounding)

| Coupon bond information
used to generate the zero curve. An | |

| Maturity date of the bond, as a serial date number. Use | |

| Coupon rate of the bond, as a decimal fraction. | |

| (Optional) Redemption or face value of the bond. Default = 100. | |

| (Optional) Coupons per year of the bond, as an integer. Allowed values are 0, 1, 2 (default), 3, 4, 6, and 12. | |

| (Optional) Day-count basis of the bond. 0 = actual/actual (default) 1 = 30/360 (SIA) 2 = actual/360 3 = actual/365 4 = 30/360 (BMA) 5 = 30/360 (ISDA) 6 = 30/360 (European) 7 = actual/365 (Japanese) 8 = actual/actual (ICMA) 9 = actual/360 (ICMA) 10 = actual/365 (ICMA) 11 = 30/360E (ICMA) 12 = actual/actual (ISDA) 13 = BUS/252

when | |

| Column vector containing
the yield to maturity of each bond in | |

| Settlement date, as a scalar serial date number. This represents time zero for deriving the zero curve, and it is normally the common settlement date for all the bonds. | |

| (Optional) Scalar that sets
the compounding frequency per year for the output zero rates in | |

| Annual compounding | |

| Semiannual compounding (default) | |

| Compounding three times per year | |

| Quarterly compounding | |

| Bimonthly compounding | |

uses the bootstrap method to return a
zero curve given a portfolio of coupon bonds and their yields. A zero curve consists of the
yields to maturity for a portfolio of theoretical zero-coupon bonds that are derived from
the input `Bonds`

portfolio. The bootstrap method
that this function uses does *not* require alignment
among the cash-flow dates of the bonds in the input portfolio. It
uses theoretical par bond arbitrage and yield interpolation to derive
all zero rates; specifically, the interest rates for cash flows are
determined using linear interpolation. For best results, use a portfolio
of at least 30 bonds evenly spaced across the investment horizon.
