split

Split calendar duration into numeric and duration units

Syntax

[X1,X2,...] = split(t,units)

Description

[X1,X2,...] = split(t,units) returns the calendar duration values specified in t as separate numeric arrays, one for each of the date or time units specified by units. The number of date and time units specified by units determines the number of output arguments.

Examples

Split Calendar Duration Array

Create a calendarDuration array.

T = calmonths(15:17) + caldays(8) + hours(1.2345)

T = 1×3 calendarDuration
   1y 3mo 8d 1h 14m 4.2s   1y 4mo 8d 1h 14m 4.2s   1y 5mo 8d 1h 14m 4.2s

Get the month, day, and time.

[m,d,t] = split(T,{'months','days','time'})

m = 1×3

    15    16    17

d = 1×3

     8     8     8

t = 1×3 duration
   01:14:04   01:14:04   01:14:04

Get the year, month, day, and time.

[y,m,d,t] = split(T,{'years','months','days','time'})

y = 1×3

     1     1     1

m = 1×3

     3     4     5

d = 1×3

     8     8     8

t = 1×3 duration
   01:14:04   01:14:04   01:14:04

When you request both the year and month, split carries over month values greater than 12 to the year value.

Input Arguments

t — Input calendar duration

calendarDuration array

Input calendar duration, specified as a calendarDuration array.

Data Types: calendarDuration

units — Date and time units

character vector | cell array of character vectors | string array

Date and time units, specified as a character vector, a cell array of character vectors, or a string array. Specify units only when the first input argument is the calendarDuration array, t.

The units can be one or more of the values in the table.

Value	Units t Is Split Into
'years'	years
'quarters'	quarters
'months'	months
'weeks'	weeks
'days'	days
'time'	time, in the format hours:minutes:seconds

You must specify date and time units from largest to smallest. For example, {'years','months'} is valid, but {'months','years'} is not.

Example: split(t,{'years','months','days'})

Data Types: char | cell | string

Output Arguments

X1,X2,... — Output numeric and duration values

arrays

Output numeric and duration values, returned as arrays. split returns year, month, and day values in numeric arrays and time values in duration arrays.

Data Types: double | duration

Extended Capabilities

Tall Arrays

Calculate with arrays that have more rows than fit in memory.

The split function fully supports tall arrays. For more information, see Tall Arrays.
