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

Test a character vector.

chr = 'Mary Jones'
chr = 
'Mary Jones'

tf = ischar(chr)
tf = logical
   1

Test a numeric array.

X = rand(1,3)
X = 1×3

    0.8147    0.9058    0.1270


tf = ischar(X)
tf = logical
   0

Test a string array.

str = ["Smith","Chung","Morales"; ...
       "Sanchez","Peterson","Adams"]
str = 2×3 string
    "Smith"      "Chung"       "Morales"
    "Sanchez"    "Peterson"    "Adams"  


tf = ischar(str)
tf = logical
   0

str is a string array, not a character array, so ischar returns 0.
