seconds - Duration in seconds - MATLAB (original) (raw)

Main Content

Syntax

Description

S = seconds([X](#buf%5Fvz%5F-1-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'.

Examples

X = magic(4); S = seconds(X)

S = 4×4 duration 16 sec 2 sec 3 sec 13 sec 5 sec 11 sec 10 sec 8 sec 9 sec 7 sec 6 sec 12 sec 4 sec 14 sec 15 sec 1 sec

Create a duration array.

X = hours(1) + minutes(1:4)

X = 1×4 duration 1.0167 hr 1.0333 hr 1.05 hr 1.0667 hr

Convert each duration in X to a number of seconds.

S = 1×4

    3660        3720        3780        3840

S is a double array.

Find the natural logarithm of S. The log function accepts inputs of type double.

Y = 1×4

8.2052    8.2215    8.2375    8.2532
