need help on the following...
key = 'BB';
data = cell(1,24);
data = {'BB'};
for i = size(data);
%compare key to each data on each column
if key = data;
%count number of elements that matches with key
counts = count how many times BB occurs
%number of elements that match divided by size of data
occurrence = counts/side of data

Not sure if this the correct guess.
y=sum(strcmp(yourCell,'BB'),2)/size(yourCell,2);

No loop necessary.
yourCell={'BB','AC','D','EF','BB','CD','BB','NF','BB','BB','AB';...
'BB','AC','D','BB','BB','CD','BB','BB','BB','BB','AB'};
key='BB';
y=sum(strcmp(yourCell,key),2)/size(yourCell,2);

one more question: how do I count the number of strings that do not match? Thank you so much!

notMatching=sum(~strcmp(yourCell,'BB'),2);
