YIELDMAT calculates the annual yield of a security for which the interest is payed at maturity date. @settlement is the settlement date of the security. @maturity is the maturity date of the security. @issue is the issue date of the security. @rate is the interest rate set to the security. @pr is the price per $100 face value of the security. @basis is the type of day counting system you want to use:
0 US 30/360
1 actual days/actual days
2 actual days/360
3 actual days/365
4 European 30/360
If @frequency is other than 1, 2, or 4, YIELDMAT returns #NUM! error. If @basis is omitted, US 30/360 is applied. If @basis is not in between 0 and 4, #NUM! error is returned.
