This answer, unlike other answers for other of your questions, do not require hobby nor any other non-standard package. It should compile right out of the box. Which problem do you have?

I edited the answer to add the documentclass so that it is compilable now. I also changed the formula as requested. Do you have any problem compiling it?

comment drawing a 2D-plane
It is unclear what you want. The code you provided uses the curve through keyword, which is not standard tikz. Which package comes it from? Anyway, "fixing" it by replacing by a plot[smooth cycle] coordinates {...} it results in a figure which is not related to the drawing you pasted. For example, what is the magenta circle?

You can take a look at matrix library, and the corresponding section of the manual. Of course you can also use a \foreach loop, wich can be more convenient of a large number of similar repeated nodes.
