Determine if item is character array
tf = ischar(A)
tf = ischar(A) returns
logical 1 (true) if A is
a character array and logical 0 (false)
otherwise.
Given the following cell array,
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]ischar shows that only C{1,2} is
a character array.
for k = 1:3
x(k) = ischar(C{1,k});
end
