Create a region adjacency matrix from a labeled image

I have an image matrix. After, I apply the superpixel algorithm to obtain the labeled matrix and I want to generate the adjacency matrix from this labeled image, my code is like that:

I=imread(myimage); 
SP=superpixelalgo(I);

How I can generate the adjacency matrix from SP? I need something like what is described below:

algorithm

my code is like this:

my image of size 10x10

I= myimage

// Applying my superpixels algo

L=superpixels(I);
L=

my superpixel matrix

the number of superpixels is:

SP=length(unique(L))=3; // so we have 3 regions

I want now to generate an adjacency matrix of size 3x3 for the regions

If you have the most recent version of MATLAB (R2015b), then try the function adjacentRegionsGraph in the MATLAB Central File Exchange submission called Image Graphs.
