For Loop to read rows on a cell array

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);

I rewrote the question...maybe that will help

[David Hill]

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!

[David Hill]

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

Thank you!
