EQID_inter is a numeric array.
Bnames_inter.Level is a cell array (whose first element contains the character vector '6000038').
You cannot compare a numeric array to a cell array.
Example:
% variables like yours, as far as I can tell:
Bnames_inter = table({'6000038';'6000039';'6000040'},'VariableNames',{'Level'});
EQID_inter = [6000152; 6000153; 6000154];
% confirming that these are the same as you show in the question:
Bnames_inter.Level(1)
EQID_inter(1)
try % try to compare a numeric array to a cell array
i = 1;
EQID_inter(i) == Bnames_inter.Level(i)
catch err % can't do it, show the error message (see below)
disp(err.message)
end
If you make Bnames_inter.Level a numeric array, then the comparison will work. To do that, make appropriate modifications to the code that creates Bnames_inter, or leave that code alone and convert Bnames_inter.Level after the fact.
The following conversion may or may not work (I don't know because I don't have your actual variables):
format long g % format for display purposes only
% convert Bnames_inter.Level from cell array of character
% vectors (presumed) to numeric array using str2double:
Bnames_inter.Level = str2double(Bnames_inter.Level)
% now Bnames_inter.Level is numeric, and the comparison works:
i = 1;
EQID_inter(i) == Bnames_inter.Level(i)
