In this example, we have two arrays,array1andarray2. We use thenumpy.concatenate()function to join these two arrays end-to-end, resulting in a new array that includes all elements from both input arrays in their original order. The resulting array,result, is then printed to the console. ...

视频的堆叠使用了的clips_array函数,调用语法如下: clips_array(array, rows_widths=None, cols_widths=None, bg_color = None) 参数说明: array:用于存放剪辑的二维列表,每个列表的元素都是一个列表,每个元素的列表代表在屏幕上同行显示的多个剪辑,一维列表中有多少个元素就表示在屏幕上显示多少行,每行视频有多...
concatenate : Concatenate function that preserves input masks. array_split : Split an array into multiple sub-arrays of equal or near-equal size. split : Split array into a list of multiple sub-arrays of equal size. hsplit : Split array into multiple sub-arrays horizontally (column wise) ...
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...
concatenate((x,y), axis=0) array([[3, 4], [5, 6], [7, 8]]) CopyIn the above code, we first import the NumPy library as 'np'. We then create two arrays 'x' and 'y' using the 'np.array()' function. The array 'x' contains two rows and two columns, whereas the ...
np.concatenate([np_array_1s, np_array_9s]) When you run this, it produces the following output: array([[1, 1, 1], [1, 1, 1], [9, 9, 9], [9, 9, 9]]) Notice what’s happened here. The concatenate function has combined the two arrays togethervertically. Essentially, the con...
