sir, i m using mean fn for an image, which is reshape into 64x3 double. but it shows an error i.e. "Too many input argument". why ?

   w_k = reshape(w_k,[],3);
mu = mean(w_k);

Can you check the type of w_k for us? What is the output of

whos w_k

[Matt J]

Also, tell us the output of

>> which reshape(w_k,[],3)

>> which mean(w_k)
