lweekdate (Financial Toolbox)

Date of last occurrence of weekday in month.

Syntax

d = lweekdate(wkd, y, m, g)
d = lweekdate(wkd, y, m)

Arguments

wkd: Weekday whose date you seek. Enter as an integer from 1 through 7:

1   Sunday
2   Monday
3   Tuesday
4   Wednesday
5   Thursday
6   Friday
7   Saturday
y
Year.  Enter as a four-digit integer.
m
Month.  Enter as an integer from 1 through 12.
g
Weekday that must occur after wkd in the same week.  Enter as an integer from 0 through 7, where 0 = ignore (default) and 1 through 7 are as for wkd.

Description

d = lweekdate(wkd, y, m, g)

returns the serial date number for the last occurrence of the weekday wkd in the given year y and month m, and in a week that also contains the weekday g.

Any input can contain multiple values, but if so, all other inputs must contain the same number of values or a single value that applies to all. For example, if y is a 1-by-N vector of integers, then m must be a 1-by-N vector of integers or a single integer. d is then a 1-by-N vector of date numbers.

Use the function datestr to convert serial date numbers to formatted date strings.
