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

i have this two tables querymdr & idx2 :

i want to compare the fisrt two coulmns of them , and the multiple value copy column 6 of it only

i want to have the answer like this:

what i can do? any one has an idea?

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.
