MATLAB: Error using contains function

cell arraycontainsMATLAB

when I use contains function in a loop it show me that error message, even though Raw is a cell array, and also the compilation complete and the code after if contains(Raw(i,2),serie)==1 works well.

is there a solution for that ?

I can see in your screen shot of workspace variables that your "Raw" array contains mostly NaN values.

According to your error message, the first argument of contains() must be a string array, char vector, or cell array of char vectors. "Raw" appears to be a cell array with lots of NaNs.

You probably want to just skip iterations where the input to contains() includes NaN values (or you might want to use a different method).

Hi,

if your raw contains both strings and NaN, you will need to do something like this:

raw(cellfun(@(x) isnumeric(x) && isnan(x), raw)) = {''};

If your raw contains numbers only, I would convert to an array (cell2mat) and then use isnan directly.
