3 Principles of Success (Harford)

  1. Seek out and try new things.

  2. When trying something new, do it on a scale where failure is survivable.

  3. Seek out feedback (to determine your level of success) and learn from your mistakes as you go along.

comment Conversion of binary matrix of mlf into multilinear function, any ready function for this?
You are correct! Inner[Power, Subscript[x, #] & /@ Range[7], {1, 0, 1, 0, 0, 0, 1}, Times] returns x_1x_3x_7, amazing! Now looping required, anyway excellent idea! So easy to read to consider zero/ones as powers ^-^ +1

More example: D_{1>2} is the earlier, we are clearly thinking this differently.

comment How to get monomials multiplied by each other?
Yes but my Mathematica is returning {x,3x,7x} -- oouch brackets missing?! So my version operated on the Subscript thing, not the whole thing. Thank you! +1

comment Command to change binary mlf terms into Subscripted mlf terms?
I cannot fully understand this: suppose I specify the terms with {1,3,7} to mean p_1p_3p_7 -- is it easier to get the multilinear term from it? So here terms Subscript[x, #] & /@ {1, 3, 7} and now just multiplication. Where is the multiplication?
