So you can look for that book and read the algorithm there and program it.
Or you could purchase a license for the Image Processing Toolbox.

I recently had to solve this problem without Image Processing Toolbox but this solution will only work for vector inputs.
% vector of grouped 1s, separated by 0s
v = mod(1:100,10) > 0;
% Solve without Image Processing Toolbox
vcs = cumsum(diff([0,v]) == 1); % if v is a column vector: [0;v]
L = zeros(size(v));
L(v) = vcs(v);
% Solve using Image Processing Toolbox
L2 = bwlabel(v);
% Compare outputs
isequal(L,L2) % = TRUE, they match
