Determine if input is string array
tf = isstring(A)
tf = isstring(A) returns 1 (true) if A is a string array. Otherwise, it returns 0 (false).

0
false
example
collapse all
Create different arrays, and then determine if they are string arrays.
Test a character vector.
chr = 'Mary Jones'
tf = isstring(chr)
tf = logical 0
Character vectors are not strings, so isstring returns 0.
isstring
Test a string array.
str = ["Smith","Chung","Morales"; ... "Sanchez","Peterson","Adams"]
str = 2×3 string "Smith" "Chung" "Morales" "Sanchez" "Peterson" "Adams"
tf = isstring(str)
tf = logical 1
str is a string array, so isstring returns 1.
str
Input array, specified as a scalar, vector, matrix, or multidimensional array. A can be any data type.
