# eomday

Last day of month

## Syntax

```E = eomday(Y,M) ```

## Description

`E = eomday(Y,M)` returns the last day of the year and month given by corresponding elements of the numeric arrays `Y` and `M`.

## Examples

Show the end of month for January through September for the year 1900:

```eomday(1900, 1:9) ans = 31 28 31 30 31 30 31 31 30 ```

Find the number of days during that period:

```sum(eomday(1900, 1:9)) ans = 273 ```

Because 1996 is a leap year, the statement `eomday(1996,2)` returns `29`. To show all the leap years in the twentieth century, try:

```y = 1900:1999; E = eomday(y,2); y(E == 29) ans = Columns 1 through 6 1904 1908 1912 1916 1920 1924 Columns 7 through 12 1928 1932 1936 1940 1944 1948 Columns 13 through 18 1952 1956 1960 1964 1968 1972 Columns 19 through 24 1976 1980 1984 1988 1992 1996 ```
