Syntax

Description

example

D = days(X) returns an array of days equivalent to the values in X.

  • If X is a numeric array, then D is a duration array in units of fixed-length days. A fixed-length day is equal to 24 hours.

  • If X is a duration array, then D is a double array with each element equal to the number of fixed-length (24-hour) days in the corresponding element of X.

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