Create different arrays, and then determine if they are string arrays.

Test a character vector.

Character vectors are not strings, so isstring returns 0.

Test a string array.

str = ["Smith","Chung","Morales"; ... "Sanchez","Peterson","Adams"]

str = 2×3 string "Smith" "Chung" "Morales" "Sanchez" "Peterson" "Adams"

str is a string array, so isstring returns 1.
