Duration in days
D = days( returns an array of days
equivalent to the values in
Xis a numeric array, then
durationarray in units of fixed-length days. A fixed-length day is equal to 24 hours.
doublearray with each element equal to the number of fixed-length (24-hour) days in the corresponding element of
days function converts between
double values. To display
a duration in units of days, set its
Format property to
Create Duration Array of Fixed-Length Days
X = magic(2); D = days(X)
D = 2x2 duration 1 day 3 days 4 days 2 days
Add each number of fixed-length days to the current date and time.
t = datetime('now') + D
t = 2x2 datetime 20-Aug-2023 14:31:45 22-Aug-2023 14:31:45 23-Aug-2023 14:31:45 21-Aug-2023 14:31:45
Convert Durations to Numeric Array of Days
X = hours(23:20:95) + minutes(45)
X = 1x4 duration 23.75 hr 43.75 hr 63.75 hr 83.75 hr
Convert each duration in
X to a number of days.
D = days(X)
D = 1×4 0.9896 1.8229 2.6562 3.4896
X — Input array
