Return true if string array is sorted.
TF = issorted (str) returns a logical scalar TF,
which is true, if the string array str is sorted in
ascending order, and false otherwise.
TF = issorted (str, dim) returns a logical
scalar TF, which is true, if the string array str
is sorted in ascending order along the dimension dim, and
false otherwise.
TF = issorted (str, direction) returns a logical
scalar TF, which is true, if the string array str is
sorted in the direction specified by direction, and false
otherwise. direction can be any of the following options:
'ascend', which is the default, checks if 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 missing elements.
'strictdescend' checks if elements are in descending order
and there are no duplicate or missing elements.
'strictmonotonic' checks if elements are either in
ascending or descending order and there are no duplicate or missing
elements.
TF = issorted (…, specifies where missing elements ('MissingPlacement',
MP)<missing>) 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.
