Now, we can apply the add_one_ufunc to a NumPy array: python. arr = np.array([1,2, 3])。 result = add_one_ufunc(arr)。 print(result)。 Output: [2 3 4] In this example, the add_one_ufunc applies the add_one function element-wise to the array `arr`, resulting in a new ...
To read data from such files into Numpy arrays we can use the numpy.genfromtxt function. 案例说明 我们以数字示波器采集的实验产生的三角波 (triangular waveform) 为例,它是包含数据信息的表头,以 .txt 格式存储的文本文件。 1 2 3 4 5 6 7 8 9 10 11 12 13 Type: raw Points: 16200 Count: ...
