MATLAB: Remove rows with certain element in cell arrays

cell

In the following data set, I want to keep only the rows with 'Hourly' element, thus only row 2. I use the following, but it doesn't work. Can anybody help me?

data={'s' 'e' 'daily'; 't' 'c' 'hourly'; 'm' 'b' 'daily'}

 data_2 = cellfun(@(x) x(x(:,3)=='Hourly'), data, 'UniformOutput', false)

Did you mean to write:

x{:,3}=='Hourly'

The curly-braces thing trips me up all the time =)

Hi,

You can use strfind function to determine the presence of elements in you char array.

matrix = ['a','b','d','f';
          'c','t','a','g';
          'f','a','n','p';
           'd','b','a','b'];
word = 'ab';
for i=1:length(matrix)
    str = matrix(i,:);
    idxL2R = strfind(str,word);
    idxR2L = strfind(str,flip(word));
    result = ['for string = ',str,' indexL2R while searching for word = ',word,
             ' is = ',int2str(idxL2R), ' indexR2L is = ', int2str(idxR2L)];
    disp(result);
end
