isduration

Determine if input is duration array

Syntax

tf = isduration(t)

Description

tf = isduration(t) returns logical 1 (true) if t is a duration array. Otherwise, it returns logical 0 (false).

Examples

Determine If Array Contains Duration Values

Determine if the output of an arithmetic calculation is a duration array.

Subtract a datetime array from another.

t1 = datetime(2014,03,16:17);
t2 = datetime(2014,03,20);
dt = t2 - t1

dt = 1x2 duration
   96:00:00   72:00:00

Determine if the output is a duration array.

tf = isduration(dt)

tf = logical
   1

Input Arguments
