MATLAB: How to denoise raw EEG data with MATLAB

eegMATLABnoise filter

I made the program which would filter out the noise from raw EEG data, however, I could not implement the code. Could you please tell me what is wrong with this program? The program is down below.
   function OutputEEG = MyEEGFilter(InputEEG,fs)
   fs=SampleRate;
   lowEnd = 3; % Hz

   highEnd = 70; % Hz
   filterOrder = 2; % Filter order (e.g., 2 for a second-order Butterworth filter). Try other values too
   [b, a] = butter(filterOrder, [lowEnd highEnd]/(fs/2)); % Generate filter coefficients
   d = designfilt('bandstopiir','FilterOrder',8, ...
               'HalfPowerFrequency1',49,'HalfPowerFrequency2',51, ...
               'DesignMethod','butter','SampleRate',fs);
   InputEEG=double(InputEEG);
   Foutput(1,:) = filtfilt(d,InputEEG(1,:));
   Foutput(1,:) = filtfilt(b,a,Foutput(1,:));
   end

Best Answer

How are you calling it? And attach InputEEG and fs in a .mat file so we can call it ourselves with your data. And be sure to define OutputEEG. Maybe it's as simple as
OutputEEG = Foutput;
As the last line of your program.
