HI I have a 2D array like this:
and a cell array:
I want to search elements of cell array in 1st column of 2D array. Like 2nd row of cell array has 4 and 3, it is present in 1st column of 2D array, it should display both rows (and all other elements as zero).

@Tha saliem: I notice that you are clearly using my code from your earlier question:
Is there a reason why you do not accept my answer... even though you are using my answer?
Also it would be much easier if you actually told us what you are trying to achieve, rather than trying to solve these small tasks. Then we could help you to develop a solution for your main task, rather then waste time trying to figure out solutions (that you do not accept) to every small task:

Im really sorry I was using it through cell phone and i clicked on Accept answer at the time when i commented on that. I didn't even know that it was not accepted. Sorry for this. and thanks for your code it really helped. The main task is quite large and i am working on it from 4 to 5 weeks so it will be difficult for me to sum it up.

M = [0 1
1 0
2 1
3 0
4 1
5 0
6 0];
C = {[];[4;3];[3;1;4];2;[1;3;2;4];5;5};
output = cellfun(@(x)M(sort(x),:),C,'UniformOutput',false);

Thank you so much. But this is comparing based on indexes, I want to compare it based on values of first column.
