symysgames Posted October 27, 2016 Share Posted October 27, 2016 Hello I am searching for good auto lisp code for doing algebra with imaginary numbers. Will be very grateful for any efficient answer. Thank you:D Quote Link to comment Share on other sites More sharing options...
BIGAL Posted October 28, 2016 Share Posted October 28, 2016 Its in the imaginary lisp code library Quote Link to comment Share on other sites More sharing options...

Manila Wolf Posted October 28, 2016 Share Posted October 28, 2016 In case anyone think the original post flippant:https://en.wikipedia.org/wiki/Imaginary_number I am indeed guilty of showing a lack of seriousness. For that I sincerely apologise to the OP. Quote Link to comment Share on other sites More sharing options...
symysgames Posted October 28, 2016 Author Share Posted October 28, 2016 Thank you for your answer, Does anyone have a link for the imaginary lisp code library, I found one but seems obsolete. It seems the best way is to treat them as vectors and define every operation. I am not looking for information on imaginary numbers, In fact I use autocad and auto lisp to generate patterns from mathematical expressions to study Integers. Just discovered thanks to autocad that every integer belongs to one and only one of the two expressions :Z1 = x^2 + 2x(y+1) + y^2 + y +1 and Z2 = x^2 + 2x(y+1) + y^2 + 3y +2 when x,y > 0 or = 0 When x,y take negative values, Z1 and Z2 take similar values . But it's when they take imaginary values and when Z1 and Z2 are integers that I am studying now. From these two relations I discovered that there are many ways to factorise integers. Doing math with autocad seems a bit crazy as there are many math programs, but I am an artist and I love integers. I'm working on a exhibition I would like to do, . If you have any interesting links for me. Thank you all and have a good day. Quote Link to comment Share on other sites More sharing options...
nukecad Posted October 30, 2016 Share Posted October 30, 2016 Have you looked at Lee Mac's lisps for creating fractals in Autocad? They use imaginaries. http://www.lee-mac.com/fractals.html Quote Link to comment Share on other sites More sharing options...
Lee Mac Posted October 30, 2016 Share Posted October 30, 2016 I have also published a small library for working with complex numbers. Quote Link to comment Share on other sites More sharing options...

symysgames Posted October 31, 2016 Author Share Posted October 31, 2016 Thank you again , I find autocad and autolisp such a good combination for exploring mathematics with a more artistic approach , you can create your own mappings , just need to keep a good visualisation of what you are doing. I was wondering when T was going to fall upon complex numbers , then I realised they were staring at me. I don't see myself as a mathematician but as an artist who loves numbers and especially Integers . I know my perspective is quite original, Imagine a mapping composed of infinite many similar mappings The mapping is composed of tiny blocks of the size of a pixel containing attributes. One difficulty I encountered was counting these blocks with selection sets. I found that autolisp does not like empty selection sets and the only solution I found was making certain the selection sets were never empty. The other problem occurred when the blocks became the size of a pixel, I found that I was selecting too many of them because of the width of the selecting line. So I stead of using the drawing I used algebra and that's ok now. Quote Link to comment Share on other sites More sharing options...
