islogical

Determine if item is a logical array

Syntax

• tf = islogical(A)
  

Description

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

Examples

Given the following cell array,

• C{1,1} = pi;
  C{1,2} = 1;
  C{1,3} = ispc;
  C{1,4} = magic(3)
  
  C = 
  
      [3.1416]    [1]    [1]    [3x3 double]
  

islogical shows that only C{1,3} is a logical array.

• for k = 1:4
  x(k) = islogical(C{1,k});
  end
  
  x
  
  x =
  
       0     0     1     0
