DATEPART

Extract decimal yr/month/day/hr/min/sec from a datenum. More versatile than datevec.

X = DATEPART(DATE,'part') returns the date 'part' (year, month,day, hour, minute or second) of the datenum date with the decimal equivalent of the trailing date parts in the units of 'part'. DATE can be scalar, vector or array and X will be of the some size and shape.

[X1,X2,...] = DATEPART(DATE,'part1','part2',...) returns each decimal value corresponding to each part input argument.

Acceptable string specifiers for 'part' are:
Year: 'year','yr','years','yrs'
Month: 'month','mn','months','mns'
Day: 'day','days'
Hour: 'hour','hours','hr','hrs'
Minute: 'minutes','minutes','min','mins'
Second: 'second','seconds','sec','secs'

Examples:
>> A = datenum('14-Jul-2007 15:05:12')
>> datepart(A,'min')
ans =
5.2000
>> floor(datepart(A,'min'))
ans =
5
>> format bank
>> datepart(A,'year')
ans =
2007.53
>> [day,yr] = datepart(A,'day','year')
day =
14.63
yr =
2007.53
