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

Test a cell array of character vectors.

C1 = {'Smith','Chung','Morales';...'Sanchez','Peterson','Adams'}

C1 =2×3 cell array'Smith' 'Chung' 'Morales' 'Sanchez' 'Peterson' 'Adams'

tf = iscellstr (C1)

tf =logical1

Every cell ofC1contains a character vector, soiscellstrreturns1.

ConvertC1to a string array and test it.

str = string(C1)

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

tf = iscellstr (str)

tf =logical0

stris a string array, not a cell array, soiscellstrreturns0.

Test a cell array that contains elements of different data types.

X = rand(1,3); C2 = {'red','blue',X}

C2 =1×3 cell array'red' 'blue' [1×3 double]

tf = iscellstr (C2)

tf =logical0

C2has a cell that does not contain a character vector, soiscellstrreturns0.
