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 =2x3 cell{'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 =2x3 string"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'} {[0.8147 0.9058 ... ]}

tf = iscellstr(C2)

tf =logical0

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