can anyone help me to get output of this for loop in matrix like if number of samples are 5 then filtered signal x should be first sample in first column,second sample in second and likewise. it is getting overwrite output for filtered signal x.

for k = 1:length(AudioFile)
 filename = AudioFile(k).name;
  [y,fs] = audioread(filename);
 
 

y = medfilt1(y(k,:),3);   %spike removal of signal 

 [b,a]    = butter(3,[25,900]/(fs/2), 'bandpass');    %bandpass filtering with order 6
 x       = filter(b,a,y);
