iscellstr - Determine if input is cell array of character vectors - MATLAB (original) (raw)
Main Content
Determine if input is cell array of character vectors
Syntax
Description
tf = iscellstr([A](#bvidcsp-A)) returns logical 1 (true) if A is a cell array of character vectors (or an empty cell array), and logical 0 (false) otherwise. A cell array of character vectors is a cell array where every cell contains a character vector.
Examples
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 {'Smith' } {'Chung' } {'Morales'} {'Sanchez'} {'Peterson'} {'Adams' }
Every cell of C1 contains a character vector, so iscellstr returns 1.
Convert C1 to a string array and test it.
str = 2×3 string "Smith" "Chung" "Morales" "Sanchez" "Peterson" "Adams"
str is a string array, not a cell array, so iscellstr returns 0.
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 0.1270]}
C2 has a cell that does not contain a character vector, so iscellstr returns 0.
Input Arguments
Input array, specified as a scalar, vector, matrix, or multidimensional array. A can be any data type.
