arr1=np.array([1,2,3])arr2=np.array([4,5,6])arr3=np.array([7,8,9])result=np.concatenate((arr1,arr2,arr3))print("numpyarray.com - Concatenated multiple 1D arrays:",result) Python Copy Output: 这个例子展示了如何将三个一维数组连接成一个更长的数组。
中文:在Python中,我们可以使用加号运算符来连接两个字符串。 英文:To form a single list, you need to concatenate all the sublists. 中文:为了形成一个单一的列表,你需要将所有子列表连接起来。 英文:The concatenate function in NumPy is used to join two or more array...

The arrays must have the same shape, except in the dimension corresponding toaxis(the first, by default). axis : int, optional The axis along which the arrays will be joined. Default is 0. concatenate中含有两个参数,第一个参数就是进行 ...
Usehstackto stack arrays in sequence horizontally (column wise). np.hstack([p,2*p]) Output: array([[1, 1, 1, 2, 2, 2], [1, 1, 1, 2, 2, 2]]) --- 作者:故乡月zyl 原文:https://blog.csdn.net/zyl1042635242/article/details...
1. stack(arrays, axis=0) Join a sequence of arrays along a new axis. The `axis` parameter specifies the index of the new axis in the dimensions of the result. For example, if ``axis=0`` it will be the first dimension and if ``axis=-1`` it will be the last dimension. ...
