I AM TRYING TO FIND ALL CELLS IN A WICH EQUAL B THE CODE :
for j=1:length(defs) % loop over Mdr of defib
querymdr=data2(:,1); % "A" save MDR numbers
y=alldata(:,1); % "B"
idx= find(y==querymdr); % FIND ALL CELLS WHICH IS EQUAL
it gives me an error in
idx= find(y==querymdr);
what was i write wrong?

querymdr has 5*1 cells, y has 37*1 cells
i want to find all the cells in y that matched(has the same numeric value) with querymed.
thats the whole file... i choose 5 cells in the first column (left).
and want to know all the cell in the first coulmn (right) which = it

querymdr = cellfun(@(C) C{1}, data2); %presuming the first entry is a scalar!
ally = cellfun(@(C) C{1}, alldata); %presuming the first entry is a scalar!
Now you have two numeric vectors to compare. What you would do from there would depend on whether you are expecting multiple matches for each entry.

What error message does it give you?
Please show
class(data2)
class(alldata);
