Is it possible to apply a low pass filter to a data matrix? If so, how?
I have, for example, a matrix M (527x15). I take the first column of this matrix C=M(:,1). And plot this column:

what can I do to smooth the signal?
I thought I was using a low pass filter. But I do not know how I can do it.
If I wanted to use other columns of the matrix, is it possible to apply the low pass filter to the entire matrix M?
Please help me

From the documentation:
‘filtfilt operates along the first array dimension of x with size greater than 1.’
