Bond duration given yield

**In R2017b, the specification of optional input arguments has changed. While the
previous ordered inputs syntax is still supported, it may no longer be supported in a
future release. Use the optional name-value pair inputs: Period,
Basis, EndMonthRule,
IssueDate,FirstCouponDate,
LastCouponDate,
StartDate,Face,
CompoundingFrequency, DiscountBasis, and
LastCouponInterest.**

`[ModDuration,YearDuration,PerDuration] = bnddury(Yield,CouponRate,Settle,Maturity)`

`[ModDuration,YearDuration,PerDuration] = bnddury(___,Name,Value)`

computes the Macaulay and modified duration of `ModDuration`

)`NUMBONDS`

fixed
income securities given yield to maturity for each bond.

`bnddury`

determines the Macaulay and modified duration for a
bond whether the first or last coupon periods in the coupon structure are short or
long (that is, whether the coupon structure is synchronized to maturity).
`bnddury`

also determines the Macaulay and modified duration
for a zero coupon bond.

`[`

adds optional name-value pair arguments. `ModDuration`

,`PerDuration`

] = bnddury(___,`Name,Value`
