Reshape Cell to Matrix

So I'm having an issue adjusting this function to work with my actual dataset and it may be because I still don't understand the function quite right. (See answer to my original question here -
My actual dataset format is as follows....
data = {'06/03/2011','00163T10'
How would I go about using the arguments above with a dataset in this format. Ultimately, I am attempting to create a logical matrix of whether the ticker was in or out (1 or 0) for each given day using the accumarray function that Andrei began to help me with in the example posted above.

try this cod (small corrected, typo)
d1 = datenum(data(:,1),'mm/dd/yyyy');
[a1,c1,c1] = unique(d1);
[a2,c2,c2] = unique(data(:,2));
out1 = accumarray([c1,c2],ones(numel(c1),1),[max(c1),max(c2)],@(x){x},{0});
out = [{NaN}, a2'; cellstr(datestr(a1,'mm/dd/yyyy')),out1];

Sorry for being so slow to respond to this. You answer worked brilliantly and I have been using it for a while now.
Thanks Andrei,
