I'm learning Mathematica in order to work with Linear Algebra. I found a good post here about matrix manipulation, but realized that the author used conventions that I couldn't find documented in the Wolfram explanations. Can someone point me to where these are explained.
Range@12 - I see that it's the same as Range. Where is the use of @ defined?
~Partition~ 3 - Again I think I see the use of the tilde, but couldn't find where its use is defined. The documentation seems to say its an "infix" without definition.
// And yet again I think I see what it means, but want to understand specifically. Where is it explained?
