Return true if categorical matrix rows are sorted.
TF = issortedrows (C) returns a logical scalar
TF, which is true, if the rows in the 2-D categorical array
C are sorted in ascending order, and false otherwise.
TF = issortedrows (C, col) returns a logical
scalar TF, which is true, if the categorical array C
is sorted according to the columns specified by the vector col, and
false otherwise. col must explicitly contain non-zero
integers whose absolute values index existing columns in C.
Positive elements sort the corresponding columns in ascending order,
while negative elements sort the corresponding columns in descending
order.
TF = issortedrows (C, direction) checks if the
rows in C are sorted according to the specified direction, which
can be one of the following options:
'ascend', which is the default, checks is elements are in
ascending order.
'descend' checks if elements are in descending order.
'monotonic' checks if elements are either in ascending or
descending order.
'strictascend' checks if elements are in ascending order
and there are no duplicate or undefined elements.
'strictdescend' checks if elements are in descending order
and there are no duplicate or undefined elements.
'strictmonotonic' checks if elements are either in
ascending or descending order and there are no duplicate or undefined
elements.
Alternatively, direction can be a cell array of character vectors specifying the sorting direction for each individual column of C, in which case the number of elements in direction must equal the number of columns in C.
TF = issortedrows (C, col, direction)
checks if the rows in the categorical array C are sorted according
to the columns specified in col using the corresponding sorting
direction specified in direction. In this case, the sign of the
values in col is ignored. col and direction must have
the same length, but not necessarily the same number of elements as the
columns in C.
TF = issortedrows (…, specifies where missing elements ('MissingPlacement',
MP)<undefined>) are
placed with one of the following options specified in MP:
'auto', which is the default, places missing elements last
for ascending sort and first for descending sort.
'first' places missing elements first.
'last' places missing elements last.
