答案1

有几个问题。

两个都很容易解决。

首先，不要在 后留空行\foreach。TikZ 希望读到循环末尾而不中断任何段落。

其次，切勿$$在 LaTeX 文档中使用。这样做会使 TikZ 产生混淆，但无论如何，这样做都是不好的。在这种情况下，只需将$$s改为$s 即可。

第三个不太容易解决，你需要决定你的意思以及你需要做什么。你指定的图超出了 TeX 可以处理的最大尺寸。为了让代码编译，我不得不注释掉这些：

0除了@cfr 提到的注释之外，我认为这里真正的问题是在第一个表达式的域中包含：

plot(\x,{1-abs((\x))+0.1*2.718281828^((-1)/0.1)*(1-2.718281828^((1-abs(\x))/0.1))})

如果 ，上述表达式中的最后一个括号2.718281828^((1-abs(\x))/0.1))计算为22026.4657576099> 。pgfmanual 说明如下：16383.99999\x = 0

需要注意的是，所有计算在任何时候都不能超过 ± 16383.99999，因为底层计算依赖于 TeX 维度。这意味着许多底层计算必然是近似的，而且速度也不是很快。毕竟，TeX 是一种排版语言，不太适合相对高级的数学运算。但是，可以按照第 76 节所述更改计算

根据 TeX Book

16383.99998 pt（TeX 的最大尺寸）

为了解决这个问题，您可以在这个域的一半上各绘制两个图，例如-1:-.1和.1:1。

要放大图片使用x=6.0cm,y=6.0cm并进行\footnotesize全局设置。
