tile的用法

tile函数在numpy库中

python文档如下：

tile(A, reps)
    Construct an array by repeating A the number of times given by reps.

通过由reps给出的参数，重复A相应的次数，构造一个新的数组
    
    If `reps` has length “d“, the result will have dimension of
    “max(d, A.ndim)“.
    
    If “A.ndim < d“, `A` is promoted to be d-dimensional by prepending new
    axes. So a shape (3,) array is promoted to (1, 3) for 2-D replication,
    or shape (1, 1, 3) for 3-D replication. If this is not the desired
    behavior, promote `A` to d-dimensions manually before calling this
    function.
    
    If “A.ndim > d“, `reps` is promoted to `A`.ndim by pre-pending 1’s to it.
    Thus for an `A` of shape (2, 3, 4, 5), a `reps` of (2, 2) is treated as
    (1, 1, 2, 2).
