Syntax
Description
Examples
Determine If a fixed.Interval
O
bject Is NaN
Create a fixed.Interval
object. Use the isnan
function to determine whether the Interval
object is not a number.
interval = fixed.Interval({-pi,pi},{nan,1},{nan,nan}); bool = isnan(interval)
bool = 1x3 logical array
0 1 1
The output is a logical 1 when the interval contains one or more NaN elements, and 0
otherwise.
Input Arguments
A
— fixed.Interval
object
fixed.Interval
object | array of fixed.Interval
objects
Input fixed.Interval
object, specified as a fixed.Interval
object, or an array of fixed.Interval
objects.
Output Arguments
bool
— Indicates whether elements of A are NaN
true | false | logical array
Indicates whether the fixed.Interval
object
A
is NaN, returned as a logical value.
When A
is an array of Interval
objects, the
output is an array of logical values of the same size as A
.
