Error to applying ismember for cell arrays

3 views (last 30 days)
I really thanks in advance any help. I am trying to use the below command to find any variable from the A member of the B, but encountering with the error. Welcome any suggestion.
[~,JINDX] = cellfun(@(x)(ismember(B,x)),A,'Uni',false);
Error using cell/ismember (line 34)
Input A of class cell and input B of class char must be cell arrays of strings, unless one is a string.
Error in @(x)(ismember(B,x))
34 error(message('MATLAB:ISMEMBER:InputClass',class(a),class(b)));

It is not clear what you expect. Cell array A contains Rx1 character arrays,e.g.:
>> A{1}
ans =
while cell array B contains scalar numerics (which would be much better store in once numeric array):
>> B{1}
ans = 6900805
Do you expect that Rx1 character vector to be equivalent to that numeric scalar? For example:
>> Anum = str2double(cellfun(@(v)v(:).',A,'uni',0));
>> Bnum = [B{:}];
>> idx = ismember(Bnum,Anum)
idx =
1 0 0 0 0 0 0 0 0 0

load("example.mat") ;
N = length(A) ;
A1 =zeros(N,1) ;
for i = 1:N
A1(i) = str2num(A{i}') ;
B1 = cell2mat(B)' ;
[c,ia] = ismemebr(A1,B1) ;

Dear KSSV,
the problem is when I want to use ia as index to find the corresponding variable,
>> C = D(ia);
Subscript indices must either be real positive integers or logicals.
