C#模式-与图片相同吗? [英] C# pattern - is it same as in image?

问题描述

我不太确定这与我在C#中编写的与该图像是否相同的模式吗?
代码:

Im not really sure about that is it same pattern i wrote in c# as in this image?
code:

-Math.Cos(x1) * Math.Cos(x2) * Math.Pow(Math.E, Math.Pow(-(x1 - Math.PI), 2) - Math.Pow((x2 - Math.PI),2));

正确的图案:

Thank u you for help

推荐答案

将-"放入Math.Pow(-(x1 - Math.PI), 2)内时出现了错误，该方法不是最好的.由于性能，我也不会在正方形上使用Pow ，而是会使用Exp 函数:

v

Acutally made error in putting the "-" inside the Math.Pow(-(x1 - Math.PI), 2), and the approach is not the best. I would also not use the Pow for square because of perfomance, and would use the Exp function:

v

ar VALUE = - Math.Cos(x1) * Math.Cos(x2) * Math.Exp(-(x1 -nu) *(x1 - Math.PI) -(x2 -nu) * (x2 -Math.PI));
