numpy.multiply(array1, array2, out=None) multiply() Arguments Themultiply()function takes following arguments: array1andarray2- two input arrays to be multiplied element-wise out(optional) - the output array where the result will be stored Note:array1andarray2must have the same shape unless on...
如果a和b都是 1-D arrays,它的作用是计算内积。(不进行复共轭) >>>np.dot(3,4)12 >>>np.dot([2j,3+3j], [2j,3j]) (-13+9j) 如果a和b是 2-D arrays, 作用是矩阵的乘积,a和b的维数要满足矩阵乘积维数要求,此时推荐使用matmul或a @ b。 >>>a = [[1,0], [0,1]]>>>b = [[4,...
Python for Loop Python List Python Matrices and NumPy ArraysIn Python, we can implement a matrix as nested list (list inside a list). We can treat each element as a row of the matrix. For example X = [[1, 2], [4, 5], [3, 6]] would represent a 3x2 matrix. The first row ...

We can use two methods from thenumpymodule to achieve this. The first is by using thenumpy.multiply()function. This function works with lists and arrays, and multiplies every element from one list with the corresponding element at the other list. The final result will be stored in an array...
