1. Cell에서 empty 부분 없애는 방법
%# find empty cells emptyCells = cellfun(@isempty,a); %# remove empty cells a(emptyCells) = [];Note: a(i)==[] won't work. If you want to know whether the the i-th cell is empty, you have to use curly brackets to access the content of the cell. Also, ==[] evaluates to empty, instead of true/false, so you should use the command isempty instead. In short: a(i)==[] should be rewritten as isempty(a{i}).

2. Cell에서 empty 부분 확인해서 찾는 함수 : isempty
>> help isempty
isempty True for empty array.
isempty(X) returns 1 if X is an empty array and 0 otherwise. An
empty array has no elements, that is prod(size(X))==0.
X가 하나의 empty array 이여만 가능하지 empty와 non-empty가 섞여있는 경우라면 isempty가 전부다 0만 나옴... 거지같네;;;
