Determine if array is sorted
TF = issorted(A)
TF = issorted(A,dim)
TF = issorted(___,direction)
TF = issorted(___,Name,Value)
TF = issorted(A,'rows')
TF = issorted(
returns
the logical scalar 1 (A
)true
) when the elements of A
are
listed in ascending order and 0 (false
) otherwise.
If A
is a vector, then issorted
returns
1 when the vector elements are in ascending order.
If A
is a matrix, then issorted
returns
1 when each column of A
is in ascending order.
If A
is a multidimensional array,
then issorted
returns 1 when A
is
in ascending order along the first dimension whose size does not equal
1.
If A
is a timetable, then issorted
returns
1 when its row time vector is in ascending order. To check the ordering
of row times or variables of a timetable with additional options,
use the issortedrows
function.
TF = issorted(___,
returns
1 when direction
)A
is sorted in the order specified by direction
for
any of the previous syntaxes. For example, issorted(A,'monotonic')
returns
1 if the elements of A
are ascending or descending.
TF = issorted(___,
specifies
additional parameters for checking sort order. For example, Name,Value
)issorted(A,'ComparisonMethod','abs')
checks
if A
is sorted by magnitude.
TF = issorted(
returns
1 when the elements of the first column of a matrix are sorted. If
the first column contains repeated elements, then A
,'rows')issorted
looks
at the ordering of the second column to determine TF
.
In general, issorted
looks to the column immediately
to the right to determine TF
when the current and
previous columns have repeated elements.
If A
is a timetable, then issortedrows
checks
if the row time vector is in ascending order.
This syntax is not supported for a matrix of character vectors.
