    img=imread('img1.jpg');
[m,n,p]=size(img);
if p==3
    img=rgb2double(img);
end 
for i=1:m 
    for j=1:n
    a=img(i,j);
    taylor(img,a);
    end
  end

You will need to find a different approach. taylor analysis is not defined for numeric arrays.

A truncated taylor series can be viewed as a polynomial fitting.

Hypothetically, you could model an image by declaring it to be a surface in X and Y, and then doing a multinomial fit to it, and then replacing the image with the values projected by the multinomial.

In practice: this is likely to work very very poorly.
