I'm trying to trim the null characters off a multi-dimensional cell array that looks like this:
A={'a','b','c'; ----> desired output A={'a','b','c';
't','y',[]; 't','y',[];
[],'z',[]; [],'z',[];}
[],[],[];
[],[],[]}
When I use A(~cellfun('isempty',A)) I end up getting back a colum vector of everything but the null characters. I understand I could probably just use a for loop to find the longest column, then cut it from there, however I may be taking in a lot of data and my code is already quite slow, so I was wondering if there was any elegant/fast solutions to this problem?

>> A(any(~cellfun(@isempty,A),2),:)
ans =
3×3 cell array
{'a' } {'b'} {'c' }
{'t' } {'y'} {0×0 double}
{0×0 double} {'z'} {0×0 double}

Would seem then you're still at the learning level that spending some time working thru the excercises at the Getting Started link in the documentation would pay back many times over on time invested...
