I have the following if statement to determine a cell or a vector but i get en error or like this when i put in the file with vectors

opts = detectImportOptions(filename);

opts = setvartype(opts, 'char');

C = readcell(filename,opts);

if ~isnumeric(C)

numIdx = cellfun(@isnumeric,C);

C(numIdx) = cellfun(@num2str,C(numIdx),'UniformOutput',false);

Cnum = cellfun(@str2num,C,'UniformOutput',false);

elseif ~ischar(C)

charIdx = cellfun(@ischar,C);

C(charIdx) = cellfun(@srt2num,C(charIdx),'UniformOutput',false);

Cnum = cellfun(@str2num,C(charIdx),'UniformOutput',false);

end

Error using str2num (line 35)

Input must be a character vector or string scalar.

Error in Uni_Vib_Sol (line 33)

Cnum = cellfun(@str2num,C,'UniformOutput',false);

so the elseif statement doesn't seem to work

Can you send the sample file which you are checking the code with, so that issue can be reproduced
