drawing right N-gons |
Hi, I need to be able to draw right N-gons in PARI. Here's the steps I do 1) using polroots(), obtain a vector of Nth roots of unity: v=polroots(x^N-1) 2) Sort the list by arg(): ( I wrote a simple function to do that ) 3) Draw: psplothraw(real(v),imag(v),1) The only problem with above is that the sheet of paper is rectangular, so the image is scaled and I don't get a right N-gon. So my question is how can I scale, so that I get a right N-gon? Thanks Igor
