julia MethodError: no method matching zero(::Type{Any})

在复现一篇论文程序时，用juliav1.5 运行出现这个错误是代表啥意思呢？

[AquaIndigo]

麻烦把详细报错信息和错误代码贴上

错误的是一个矩阵。

当代码过长的时候，你可以考虑使用 https://pastebin.pl/ 来上传你的代码， 建议选则永久保存，以方便后来者（虽然这对对方网站的服务器不太友好）

[Jun]

建议定位到代码出错的地方之后，再把相关的代码用文本形式贴出来。

这里出错的大概原因是，你这个矩阵的元素类型是 Any, 然后代码某个地方call 了 类似 zero(eletype(A)) 之类的，要么保证这个Array的类型稳定，要么改下call zero 地方的代码，直接hardcode具体的类型。

[duannfei]

你好，可是我的这篇代码中没有用到zero函数，都是用的zeros函数。也没看见有那个地方定义这个矩阵的类型。
