isleap.m

This file test if a given year is a normal year or a leap year.

A script to assess if a given year (in the Gregorian Calendar system) is a leap year or not.

It returns 0 if is not a leap year,
it returns 1 if it is a leap year.

Examples:

>> isleap(1900)

ans =

0

>> A = [1200 1538 2001 ; 816 1900 1908 ; 2000 2004 2011]

A =

1200 1538 2001
816 1900 1908
2000 2004 2011

>> isleap(A)

ans =

1 0 0
1 0 1
1 1 0

It looks at the remainder of the division, if the year is divisible by 4, 100 and 400 and makes the decision according to it. (For a year ending in 00 is not a leap year unless is divisible for 400 too).
