Hi
yes, that's why I used brackets to point to the fact that these are done
in sequentially (though I messed up the order ;)
In melodic - as reported on the command line - the mean image is removed
first. From this, the mean time series is then removed.

Dear Christian,
Your answer is much more precise. Thank you.
But i have a question about this formula:
X' = X- t_mean * ones(1,V) - ones (T,1) * v_mean
If i use this formula, the matrix X' is neither centered for the rows,
neither centered for the columns.
Maybe i should first center the matrix for the rows to obtain a matrix X'
and then center this matrix X' for the columns to obtain a matrix X'' ?
Or the inverse ? That is:
first center the matrix for the columns to obtain a matrix X' and then
center this matrix X' for the rows to obtain a matrix X''
What do you think about this point?
Best regards,
