How to concatenate cell array with blank

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.

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

Hi Oleg, if i have index=[1;0;0] and string={'mean' 'min' 'max'}. As per index my output should be 'mean', how to get this. string(~index) gives ''min'' and ''max''. what is the sign to be used for getting ''mean''

[Oleg Komarov]

~ is the negation operator.

try in your command window:

~index

index

Then it should be clear what to use to get 'mean'.

Or you can simply remove the tilde and simple use index.
