datcmp

Compare two IRIS serial date numbers

Syntax

Flag = datcmp(Dat1,Dat2)

Input arguments

Output arguments

Description

The two date vectors must either be the same lengths, or one of them must be scalar.

Use this function instead of the plain comparison operator, ==, to compare dates. The plain comparision can sometimes give false results because of round-off errors.

Example

d1 = qq(2010,1);
d2 = qq(2009,1):qq(2010,4);
datcmp(d1,d2)
ans =
    0     0     0     0     1     0     0     0
