string.strcmp
string: TF = strcmp (A, B)
Compare strings.
TF is true, if string A is lexicographically equal to
B. If one input is a string array, the other input can be a string
array, a character vector, or a cell array of character vectors.
If either A or B is a string array or a cell array of character vectors, then a logical array TF of the same size is returned, containing the values described above for every member of the array. In this case, the other argument may also be a string array or a cell array of character vectors (of the same size or scalar), or a character vector.

strcmp compares strings for exact equality — the same idea as ==, kept for compatibility with the classic string functions.
a = string ({'cat'; 'dog'})
a =
2x1 string array
"cat"
"dog"
strcmp (a, 'cat')
ans = 1 0
