Description

tf = ischar(A) returns logical 1 (true) if A is a character array and logical 0 (false) otherwise.

Examples

C{1,1} = magic(3);           % double array
C{1,2} = 'John Doe';         % char array
C{1,3} = 2 + 4i              % complex double

C = 

    [3x3 double]    'John Doe'    [2.0000+ 4.0000i]
