Determine if input is string array
tf = isstring(A)
example
tf = isstring(A)returns1(true) ifAis a string array. Otherwise, it returns0(false).

Create different arrays, and then determine if they are string arrays.
Test a character vector.
chr ='Mary Jones'
chr = 'Mary Jones'
tf = isstring(chr)
tf =logical0
Character vectors are not strings, soisstringreturns0.
isstring
Test a string array. Starting in R2017a, you can create strings using double quotes.
str = ["Smith","Chung","Morales";..."Sanchez","Peterson","Adams"]
str =2x3 string"Smith" "Chung" "Morales" "Sanchez" "Peterson" "Adams"
tf = isstring(str)
tf =logical1
stris a string array, soisstringreturns1.
str
Input array, specified as a scalar, vector, matrix, or multidimensional array.Acan be any data type.
This function fully supports distributed arrays. For more information, seeRun MATLAB Functions with Distributed Arrays(Parallel Computing Toolbox).
