How can I delete som specific rows from a cell according to the matrix(see the pic). When the elementw of the Matrix are1 I must delete the same rows from the cell. Any ideas?

I think I find it Table(find(A==1),:)=[]. It was sooo easy...
Thanks for your help

What is "elementw" and "Matrix"? All we see are "Table" and "A".
If you have a cell array called ca, and you have a logical column vector "A", you can remove cells from ca where A is 1 or true like this:
caNew = ca(A==0); % Extract cells where A=0 (i.e. remove cells where A=1).
Or, equivalently
caNew = ca; % Initialize
caNew(A) = []; % Remove cells where A=1

Even easier is to use logical indexing. No need for find():
table is a built in function in MATLAB. Even though MATLAB is case sensitive, so table is different than table, it's a good idea not to use variable names that are the "same" as function names.
I could have told you this . . . if you'd been a little more careful about your question. For example you never mentioned the "Table" variable at all in your question. And you used the word "cell" in a non-MATLAB-ish way. Go here for a very good discussion of cells in MATLAB.
