I keep having trouble using the ismember function. I get an error code:
Error using cell/ismember. Input A of class cell and input B of class char must be cell arrays of character vectors, unless one is a character vector.
Here is my code:
temp = [];
for col = 21:50
x = General_Prompt(:,col);
x = table2cell(x);
x(ismember(x,'0 - Not at all')) = {'0'};
x(ismember(x,'50 - Maybe')) = {'50'};
x(ismember(x,'100 - Very much')) = {'100'};
x(ismember(x,'1 - Strongly agree')) = {'1'};
x(ismember(x,'50 - I don''t know')) = {'50'};
x(ismember(x,'100 - Strongly disagree')) = {'100'};
x(ismember(x,'1 - Not at all')) = {'1'};
x(ismember(x,'0 - Very badly')) = {'0'};
x(ismember(x,'50 - Moderately')) = {'50'};
x(ismember(x,'100 - Very well')) = {'100'};
x(ismember(x,'0 - None')) = {'0'};
x(ismember(x,'100 - Completely')) = {'100'};
x = str2double(x);
temp = [temp x];
end
temp = array2table(temp);
temp.Properties.VariableNames = General_Prompt.Properties.VariableNames(21:50);
General_Prompt = [General_Prompt(:,[2:3 6:9 12:13]) temp General_Prompt(:,51:end)];
If someone knows what is causing this, please let me know. I've attached the dataset I'm using for this. I should mention this used to be an old script from 2018 that I'm now using in 2022a and trying to figure out how to convert it to be compatible with the newer version of MATLAB
