Duration in seconds

Description

example

S = seconds(X) returns an array of seconds equivalent to the values in X.

• If X is a numeric array, then S is a duration array in units of seconds.

• If X is a duration array, then S is a double array with each element equal to the number of seconds in the corresponding element of X.

The seconds function converts between duration and double values. To display a duration in units of seconds, set its Format property to 's'.

Create a duration array.

X = hours(1) + minutes(1:4)
X = 1x4 duration array
1.0167 hr   1.0333 hr     1.05 hr   1.0667 hr

Convert each duration in X to a number of seconds.

S = seconds(X)
S = 1×4
