Indexing way to retrieve indices of nonempty elements of a cell array?
显示 更早的评论
Is there an indexing way (I couldn't figure one out) to do what this little function does:
function nonempty = findNonEmpty(cellarray)
% Find indices of non-empty array elements of cellarray
% Example:
% findNonEmpty({[], {3}, [], [], eye(100)}) returns [2 5]
nonempty = [];
for i=1:length(cellarray)
if ~isempty(cellarray{i})
nonempty(end+1) = i;
end
end

a={[], {3}, [], [], eye(100)};
b=find(~cellfun('isempty',a))
