Suppose I have a cell array,
ca = {'a' 'b' 'c' 10 10; 'c' 'e' 'f' 10 20; 'g' 'h' 'i' 20 10;}
How can I find the row containing eg. {'a'} {'b'} {'c'} at same time?

What are you trying to do? Does your cell array need to stay the way it is? Why not group the data into matrices with the same data.
ca={['abc';'cef';'ghi'],[10 10;10 20;20 10]};
[idx1,idx2]=find(ca{1}=='a');

Hi,
try to run following code, variable 'r' returns you row that contains what are you looking for:
[r c] = find(strcmp(ca,'g'));
Hope this helps.
Edit:
ValueToFind = {'g' 'h' 'i'}; %Define cell array of values to find in same row
l = length(ValueToFind);
ca = {'a' 'b' 'c' 10 10; 'c' 'e' 'f' 10 20; 'g' 'h' 'i' 20 10;};
[r_ca ~] = size(ca);
Row = zeros(r_ca,l);
for ii = 1:l
[r ~] = find(strcmp(ca,ValueToFind(ii)));
if ~isempty(r)
r = sort(r);
Row(r,ii) = 1;
end
end
r_f = find(all(Row,2));
In this way you obtain the row (r_f) where all ValueToFind are. Right now I give you this solution, by adopting a for loop cycle. I dont think that exists a one-line solution.
