I read the instructions for the smooth function, and I want to know if the input y to the function must be in column vector form.
Can I enter a row vector for smoothing ?

Hi @中祥 范
Yes, the input 'y' to the smooth function can be in either row or column vector form. If you step inside the function, the input 'y' is converted to a column vector using the statement "y = y(:)"
Hope this helps!

Ran in:
y can be any sized array. As Sameer states, it's reshaped to a column vector.
A = rand(6,5,2,8,4);
s1 = smooth(A); % 5D array
s2 = smooth(A(:)); % Column vector, same data
isequal(s1,s2) % same result
ans = logical
