在实践过程中,会经常遇到数组拼接的问题,基于numpy库concatenate是一个非常好用的数组操作函数。 1、concatenate((a1, a2, …), axis=0)官方文档详解 代码语言:javascript 代码运行次数:0 运行 AI代码解释 concatenate(...) concatenate((a1, a2, ...), axis=0) Join a sequence of arrays along an existin...
英文:The concatenate function in NumPy is used to join two or more arrays. 中文:NumPy中的concatenate函数用于连接两个或更多数组。 英文同义表达: “link” 解释:表示将两个或多个事物通过某种方式连接起来,常用于描述物理或逻辑上的连接。 “join” 解释:表示将两个或...
Syntactically, there are a few main parts of the function: the name of the function, and several parameters inside of the function that we can manipulate. In Python code, the concatenate function is typically written asnp.concatenate(), although you might also see it written asnumpy.concatenate...
To concatenate arrays in numpy, you use thenumpy.concatenate()function. Here’s a simple example: import numpy as np array1 = np.array([1, 2, 3]) array2 = np.array([4, 5, 6]) result = np.concatenate((array1, array2))
np.concatenate in Python Thenp.concatenatefunction in NumPy is designed for concatenating arrays along specified axes in Python. It is a versatile tool for combining arrays of the same shape and is particularly useful when we need to join multiple arrays along a specific axis, such as rows (ax...
In cases where a MaskedArray is expected as input, use the ma.concatenate function from the masked array module instead. Examples 代码语言:javascript 代码运行次数:0 运行 AI代码解释 >>> a = np.array([[1, 2], [3, 4]]) >>> b = np.array([[5, 6]]) >>> np.concatenate((a, b...
numpy.concatenate() functionThe numpy.concatenate() is a function is used to join two or more arrays along a specified axis.The numpy.concatenate() function can be used in various applications, such as merging two or more datasets with different variables or appending new data to an existing ...

When one or more of the arrays to be concatenated is a MaskedArray, this function will return a MaskedArray object instead of an ndarray, but the input masks arenotpreserved. In cases where a MaskedArray is expected as input, use the ma.concatenate function from the masked array module ins...
