Flag = datcmp(Dat1,Dat2)
Dat1
, Dat2
[ numeric ] - IRIS serial date numbers or vectors.Flag
[ true
| false
] - True for numbers that represent the same date.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.
