you can obtain a matrix product of twosympy.matrices.Matrixobjects using the standard multiplication operator, “*”. SymPy has also implemented support for the new standard Python operator
提供了点积所需的 @ 记号(例如,a @ b 是 a 和 b 的点积)。@ 运算符由特殊方法 __matmul__、__rmatmul__ 和__imatmul__ 提供支持,名称取自“matrix multiplication”(矩阵乘法) >>> va = Vector([1, 2, 3]) >>> vz = Vector([5, 6, 7]) >>> va @ vz == 38.0 # 1*5 + 2*6 ...
Example 3: Matrix Multiplication Matrix multiplication is a common operation in scientific computing and data analysis. Here’s how you can multiply two matrices using nested loops. # Matrices matrix1 = [ [1, 2], [3, 4] ] matrix2 = [ ...

Since this operation is not permitted, NumPy raises a ValueError, similar to the matrix multiplication operator.Instead, you need to take the transpose of one of the arguments:Python In [12]: arr_row.T Out[12]: array([[1], [2], [3]]) In [13]: sc_prod = arr_row @ arr_row....
