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 ?

You need to provide the variables (in a .mat file) that would let us run the important section of the code as follows:

load yourMATFile.mat
sizeRaw=size(Raw);
for i=2 : sizeRaw(1,1)
    if contains(Raw(i,2),serie)==1
       for j=2 : rowRMS(1,1)
           if contains(Raw(i,1),RMS(j,1))==1
               if contains(Raw(i+1,8),MeasTypeID)==1
                   Raw(i+1,9)=RMS(j,2);
               else
                   if contains(Raw(i+2,8),MeasTypeID)==1
                     Raw(i+2,9)=RMS(j,2);
                   else
                       if contains(Raw(i+3,8),MeasTypeID)==1
                         Raw(i+3,9)=RMS(j,2);
                       end
                   end
               end
           end
       end
    end
end

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).
