parametercurve object, specified as a previously created parametercurve object.
Data Types: object
Input dates, specified as a scalar or an
NPOINTS-by-1 vector using a datetime array,
string array, or date character vectors. StartDates must be earlier
than EndDates.
To support existing code, zerorates also
accepts serial date numbers as inputs, but they are not recommended.
(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.
A zero rate is the interest rate applicable to a
zero-coupon bond, which is a bond that does not pay periodic interest (coupons) but is sold
at a discount to its face value.
The return to the investor comes from the difference between the purchase price and the
face value paid at maturity.
Although zerorates supports serial date numbers,
datetime values are recommended instead. The
datetime data type provides flexible date and time
formats, storage out to nanosecond precision, and properties to account for time
zones and daylight saving time.
To convert serial date numbers or text to datetime values, use the datetime function. For example:
t = datetime(738427.656845093,"ConvertFrom","datenum");
y = year(t)
y =
2021
There are no plans to remove support for serial date number inputs.
