不同数据类型之间不支持Python Matrix Multiplication'<' 我正在使用Python,并希望从每个组的两个数据帧中得到一个计算出的数字(价格*比率): 表1:df1 表2:df2 所需输出:df 例如,对于Group='b'和Category='Multi',value=27.1*1.0+27.8*0.7+27.7*0.5+26.9*0.3=68.48 输入表:df1和df2中的'Group'和'Category'...
opencv and numpy matrix multiplication vs element-wise multiplication Guide opencv Matrix multiplicationis where two matrices are multiplied directly. This operation multiplies matrix A of size[a x b]with matrix B of size[b x c]to produce matrix C of size[a x c]. In OpenCV it is achieved ...
Numpy arrays use element-wise multiplication by default. Check outnumpy.einsumandnumpy.tensordot. I think what you're looking for is something like this: results = np.einsum('ij,jkl->ikl',factor,input) editedNov 15, 2022 at 15:52

Python In [1]: import numpy as np In [2]: np.array([[1, 2], [3, 4], [5, 6]]) Out[2]: array([[1, 2], [3, 4], [5, 6]]) NumPy provides several functions to facilitate working with vector and matrix computations. You can find more information on how to use NumPy...
Introducing NumPy Python is convenient, but it can also be slow. However, it does allow you to access libraries that execute faster code written in languages like C. NumPy is one such library: it provides fast alternatives to math operations in Python and is designed to work efficiently with...
