How can I find a string in an array of strings? Error using strfind PATTERN must be a string scalar or character vector.

Dear all,
I am currently trying to derandomize a list of filenames. I do have a derandomization sheet for this. However, whenever I am trying to run the script I wrote for this I encounter the following error:
Error using strfind
PATTERN must be a string scalar or character vector.
Error in Derandomization (line 14)
idx = find(~cellfun(@isempty,strfind(N,C)))
This is my code:
clearvars
close all
basicpath = ('C:\path');
[~,~,raw] = xlsread('filenames_new_sheet.xlsx');
T = readtable('derandomization.xlsx');
t = T{:,'Filename'}
newStr = erase(t,'_kakaka'); %get body of filenames to match
C = unique(newStr) % delete filenames that exist more than once
N = raw(:,2); runr
j = size(C)
k = size(N)
for n = 1:j
for m = 1:k
idx = find(~cellfun(@isempty,strfind(N,C)))
end
end
>> class N
ans =
'char'
>> class C
ans =
'char'
Why do I keep getting this error message everytime? And what can I do to avoid it? Thank you, everyone.
Kindly

@Hannah_Mad: please upload the some sample variables (e.g. raw and T) or the original files, and please show or describe the expected output for those exact variables/files.

Hannah, again I think you misunderstood Stephen's comment. When he said "please upload the some sample variables (e.g. raw and T) or the original files" he meant to attach 'Effekte_der_DBS_korrigiert.xlsx' or 'DDK_acoustic_durations.xlsx' using the paper clip icon. And I'm not seeing those anywhere on this page on any of your posts. We'll check back later for them.

Try contains(). Not sure what derandomize means. Do you mean sort according to some vector of values or alphanumerically?

But Hannah, I think you misunderstood. Stephen was merely pointing out the differences between ismember() and contains(). ismember() does not search substrings, while contains() does search substrings. So again, I ask did contains() work for you?
