Farshid - try using cellfun. It seems that the pn is a cell array with 38 elements and each element is a 8x1 char array. You haven't mentioned if each of the 8 characters is a single number or if all 8 combine to one (I'll assume the latter).

>> myData = load('example.mat');
>> numericData = cellfun(@(x)str2double(x'), myData.pn);

Farshid - it probably would have been easier if you had just asked for that format in the first place.

myData = load('example.mat');
myOutputData = nan(2,length(myData.pn));
for k = 1:length(myData.pn)
    data = myData.pn{k};
    myOutputData(1,k) = str2double(data(:,1)');
    if size(data,2) == 2
        myOutputData(2,k) = str2double(data(:,2)');
    end
end
