Input format of the smooth function

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!

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
