MATLAB: How to concatenate cell array with blank

Question

Hi, can anyone help me in concatenating below cell array

{'ob'  '^b'  []  '$b'}

so that output will be

{'ob'  '^b' '$b'}

this is an dynamic output so i could not identify the exact position of blank. Is there any simple method available otherwise i have to use a loop to identify the blank.

Answer 1

cs  = {'ob'  '^b'  []  '$b'};
idx = cellfun('isempty',cs);
cs  = cs(~idx);
