How to determine if an entry is cell type or others?

I wanted to have a function to remove the empty cell, Null cell, NaN in a vector:

A = [2 NaN 3] % DatawEmpty example

B = {'a' '' [] 'b'} % DatawEmpty example

what I tried to do is have a loop in which I make a judgement for each entry using following code:

            judge1 = isempty(DatawEmpty{ix});
            judge2 = isnan(DatawEmpty{ix});
            judge3 = strcmp(DatawEmpty{ix},'null');

if judge1 + judge2 + judge3 ~=0, then the entry will be removed from the vector. However, as you can see isempty/isnan/{} does not apply to vector composed of all types of data. So the code does not work for all.

So I wanted to use a judge to know the data type first. Is there any way to know that? like iscell? Thanks...

You can use the class() function to determine the class of an object.
