# perform element-wise subtraction of the two arraysresult = np.subtract(array1, array2) print(result)# Output: [2 4 3] subtract() Syntax The syntax ofsubtract()is: numpy.subtract(x1, x2, out =None, where =True, dtype =None) subtract() Arguments Thesubtract()function takes following ...
由于numpy模块是第三方库模块,因此需要进行安装。在cmd命令行窗口中输入"pip install numpy",就可以进行安装。 如果要使用numpy模块,需要进入这个模块。在python命令行窗口中输入"from numpy import *",引入numpy模块,就可以使用该模块中的数学函数了。 三角函数(Trigonometric) FunctionDescribe sin(x[, out])正弦值 ...

To stack two numpy arrays vertically, just change the value of theaxisparameter to 1: import numpy as np arr1 = np.array([1, 2, 3, 4]) arr2 = np.array([5, 6, 7, 8]) # Vertical (column-wise) stacking #1 arr_stacked = np.stack([arr1, arr2], axis=1) ...
Consider the example below where we created a 2-dimensional array and inserted two columns: import numpy a = numpy.array([[1, 2, 3], [4, 5, 6]]) b = numpy.array([[400], [800]]) newArray = numpy.append(a, b, axis = 1) ...
In the below example, you add two numpy arrays. The result is an element-wise sum of both the arrays. import numpy as np array_A = np.array([1, 2, 3]) array_B = np.array([4, 5, 6]) print(array_A + array_B) [5 7 9] ...
