ischar

Determine if item is a character array

Syntax

• tf = ischar(A)
  

Description

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

Examples

Given the following cell array,

• C{1,1} = magic(3);
  C{1,2} = 'John Doe';
  C{1,3} = 2 + 4i
  
  C = 
  
      [3x3 double]    'John Doe'    [2.0000+ 4.0000i]
  

ischar shows that only C{1,2} is a character array.

• for k = 1:3
  x(k) = ischar(C{1,k});
  end
  
  x
  
  x =
  
       0     1     0
