date2time - Time and frequency from dates

Settle

Settlement date. A vector of serial date numbers or date strings.

Maturity

A vector of serial maturity dates.

Compounding

Scalar value representing the rate at which the input zero rates were compounded when annualized. This argument determines the formula for the discount factors:

• Compounding = 1, 2, 3, 4, 6, 12

• Disc = (1 + Z/F)^(-T), where F is the compounding frequency, Z is the zero rate, and T is the time in periodic units, for example, T = F is one year.

• Compounding = 365

• Disc = (1 + Z/F)^(-T), where F is the number of days in the basis year and T is a number of days elapsed computed by basis.

• Compounding = -1

• Disc = exp(-T*Z), where T is time in years.

Basis

(Optional) Day-count basis of the instrument. A vector of integers.

• 0 = actual/actual (default)

• 1 = 30/360 (SIA)

• 2 = actual/360

• 3 = actual/365

• 4 = 30/360 (PSA)

• 5 = 30/360 (ISDA)

• 6 = 30/360 (European)

• 7 = actual/365 (Japanese)

• 8 = actual/actual (ISMA)

• 9 = actual/360 (ISMA)

• 10 = actual/365 (ISMA)

• 11 = 30/360E (ISMA)

• 12 = actual/365 (ISDA)

• 13 = BUS/252

EndMonthRule

(Optional) End-of-month rule. A vector. This rule applies only when Maturity is an end-of-month date for a month having 30 or fewer days. 0 = ignore rule, meaning that a bond's coupon payment date is always the same numerical day of the month. 1 = set rule on (default), meaning that a bond's coupon payment date is always the last actual day of the month.
