要做什么吗?近2月14日,什么,oh what will you get your sweet one? Your very own osculating curve? The one who rounds you up every day? Who's always acute even when you're obtuse?
不用担心,我的朋友们!MATLAB社区博客已涵盖您。我们一直在努力工作,通过文件交换,寻找您需要的东西。因为没有什么能像一束精致的代码(及其随附的图像)那样说“我爱你”。
But wait... there's more! Don't just pique their interest when you can bowl them over.
As an extra floral bonus. I'm going to give you something written by Alison Eele, from our UK office. Alison fashioned this from an algorithm originally written by Paul Nylander (you'll want to check out his good work here:
数学艺术品)。
花算法来自保罗,但这首诗都是艾莉森!我建议您在送花时背诵它。
艾莉森·埃勒(Alison Eele)的情人节诗
玫瑰是[1,0,0]
紫罗兰是[0,0,1]
Matlab说数学
(也是诗歌!)
现在,如果那不会在情人节那天给您带来幸福,为什么我不知道会怎样。
祝你好运!

% combine to form a full flower map
Violet_map = [gold_map;blue_map];
% Now lets plot it and try and pick an attractive angle
