From: Norberto Barroca on 29 Dec 2009 10:34
When I make this:

bucket(1)=dlnode(1);
bucket(2)=dlnode(2);
bucket(1).Data(length(bucket(1).Data))=[];
bucket(2).Data(length(bucket(2).Data))=[];

bucket.Data

if(isempty(bucket.Data))
fprintf('isempty')
else
fprintf('notempty')

end
I have this error:
??? Error using ==> isempty
Too many input arguments.

Error in ==> beta at 49
if(isempty(bucket.Data))


Can someone help me?

Hi Norberto,
In you call to isempty enclose the bucket.Data in square brackets so:
bucket(1)=dlnode(1);
bucket(2)=dlnode(2);
bucket(1).Data(length(bucket(1).Data))=[];
bucket(2).Data(length(bucket(2).Data))=[];
bucket.Data
if(isempty([bucket.Data]))
fprintf('isempty')
else
fprintf('notempty')
end

Hope this helps
