相关疑难解决方法(0)

我是第一次进入SciPy LinAlg模块，并且看到了以下功能：

def _makearray(a):
    new = asarray(a)
    wrap = getattr(a, "__array_prepare__", new.__array_wrap__)
    return new, wrap

到底是__array_wrap__做什么的？我找到了文档，但是我不明白这个解释：

 At the end of every ufunc, this method is called on the input object with the
 highest array priority, or the output object if one was specified. The ufunc-
 computed array is passed in and whatever is returned is passed to the user. 
 Subclasses inherit a default implementation of this method, which transforms the
 array into a new instance …
