MATLAB: Create a variable to store sets

Question

I would like to create a variable that stores a set of numbers for an arc (a,b).

S(a,b) = {1,2,3,4,5}
S(b,c) = {3,4,5} etc

but I dont know how to write it in matlab. Please help

Answer 1

Sounds like you need a cell array:

 S{set_no} = [2 3 5 6];
 S(2}      = [1 5 6 3 64 23];
