What is the benefit of using Solve over Roots? Jan21 asked How to exract the roots from “Roots”? Jan21 comment How do I write nested for-loops? @YvesKlett Can you show an example of how to write multiple lines in a "call" on Mathematica? All the examples on reference.wolfram are single line examples and its not clear how something like the above can be achieved via that! Jan21 asked How do I write nested for-loops? Jan17 asked About installing Mathematica on Ubuntu 14.04 LTS Nov18 comment Can I generate matrices with a constraint? @bills Sorry for my ambiguous language. I meant that $k$ is something chosen externally. And then the matrices have to be generated. Can you help? Nov18 comment Can I generate matrices with a constraint? Where is this value of $k$ that I would like to fix arbitrarily? I would think that any correct code should let me first choose a value of $k$ and then the matrices would be generated corresponding to that.

Oct24 awarded Nice Question Sep20 accepted Graph expansion on Mathematica Sep20 comment Graph expansion on Mathematica May be you can add some explanations to your code? Sep20 comment Graph expansion on Mathematica I am unable to understand your code. I simply don't know enough Mathematica to parse your code. How do I even give the graph as an input to your code? What is "Plus @@", "Rest", "Module" , "IntegerDigits", "Position", "[Infinity]", "Complement", "Range" - none of these make any sense to me! Can you kindly write something for beginners? Sep18 comment Graph expansion on Mathematica Given my purposes I am not sure that it will be useful for me to get approximations. I think I need exact values. Sep18 comment Graph expansion on Mathematica Can you just tell me how to run though all possible subsets of vertices of some input graph and calculate the RHS of h(G) for each of them? Sep18 comment Graph expansion on Mathematica Does this give the exact value of $h(G)$ or an approximation?
