Resizing images using interp1()

So I have got this image that I am trying to resize which I have already attached. The requirement for me is to resize the image without using the functions imresize() or immse() but use interp1(). And I have no clue where exactly to begin.

I = imread('lighthouse.png') ;
N = 1000 ; % interp1 along row
[m,n,p] = size(I) ;
iwant = zeros(m,N,p) ;
xi = linspace(1,n,N) ;
for i = 1:m
for j = 1:p
T = interp1(1:n,double(I(i,:,j)),xi) ;
iwant(i,:,j) = T ;
end
end
iwant = uint8(iwant) ;
imshow(iwant)

For each pixel you need to call it twice, once with the top and bottom neighbors, and once with the right and left neighbors.
