Python Code:import numpy as np # Create a 2D array of shape (4, 4) array_2d = np.array([[1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12], [13, 14, 15, 16]]) # Use ravel() to flatten the 2D array flattened_array = ar
在Python等编程语言中,flatten函数是一个常用的工具函数,用于简化对多维数据的处理。例如,在numpy库中,numpy.flatten()函数可以将多维数组转换为一维数组。这个函数的order参数决定了展平的顺序,默认为'C'(行优先),也可以设置为'F'(列优先)。 示例代码: python import numpy as np # 创建一个二维数组 array_2d...
arr=np.array([[1,2,3],[4,5,6]],order='F')print("Original array from numpyarray.com:")print(arr)print("Flattened with order='C':")print(arr.flatten(order='C'))print("Flattened with order='F':")print(arr.flatten(order='F'))print("Flattened with order='A':")print(arr.flatt...

python---之flatten()函数的用法与scatter函数的用法 总结:flatten()用在这里scatter的意思就是相当于e,对应于x轴,f对应于y轴,相当于画坐标点,而对mnist数据集的那段代码, 添加flatten函数的用法详见:https://blog.csdn.net/zxyhhjs2017/article/details/81152450: 部分内容来自http://blog.csdn.net/maoersong...

In the above code a 2D array y is defined with values [2, 3] and [4, 5]. The flatten() method is then called on y which returns a flattened 1D array. Therefore, the elements in the first row of y (2 and 3) come first in the flattened array, followed by the elements in the...
