中文含义:sizeof使用数组作为参数时会返回int*大小(指针的字节数),即使用sizeof测试数组类型的参数大小时得到的并不是整个数组的字节数,而是指针的字节数(数组被退化为指针使用sizeof) 原因是数组作为参数传给函数时,是传给数组首个元素的地址,而不是传给整个的数组空间,因此 sizeof(arr)这句话会报错...
provided that the array has previously been declared. An array type in the parameter list of a function is also converted to the corresponding pointer type. Information about the size of the argument
In the above code the first line of code creates a NumPy array 'x' [2, 3] and then uses np.asarray() to convert it back into an array. Since 'x' is already an array, the np.asarray() function returns 'x'. The second line of code converts the array 'x' to a float32 type...

In the above code, function foo can access an int that is part of either x or y even though x and y have different shapes. If foo were to require a coarray parameter instead, then it could accept either x or y but not both because the coarrays have different types. Furthermore...

Arrays as Method/Routine Properties Similar to using arrays as function return types, when you declare routines that take array parameters, you cannot include index type specifiers in theparameter declarations.
