I think you want to use this syntas: G = digraph(s,t)
This example is helpful: https://www.mathworks.com/help/matlab/ref/digraph.html#mw_26035adf-ff90-4a33-a8f8-42048d7e39a6
You need an element for each edge in s and t. You can achieve that with a little creativity
e = [{[1 5 7]} {[2 3 4 5 7]} {[1 2 3 5 6 7 8]} {[2 4 5 7 9]} {[1 3 6 7 9]} {[2 4 6 8 9 10]} ...
{[1 7 9 10]} {[1 3 4 5 6 9 10]} {[1 3 4 5 8 10]} {[5 9 10]}]
% Determine how many elements are in each cell
n = cellfun(@numel,e)
% Extract all values from the cell array to a target vector, t
t = [e{:}]
% use cumsum to find indices of first value from each cell
idx = cumsum([1,n(1:end-1)])
% Create s as a source vector of zeros the same size as t
s=zeros(size(t))
% Set index corresponding to fist cell value to 1
s(idx) = 1
% Use cumsum to create a vector of sources that aligns with t
s = cumsum(s)
% Create digraph
G = digraph(s,t);
plot(G,'Layout','force')
