numpy.matmul — NumPy v2.2 Manual
The matmul function implements the semantics of the @ operator introduced in Python 3.5 following PEP 465. It uses an optimized BLAS library when possible (see numpy.linalg). Examples. For 2-D arrays it is the matrix product: >>>

Sep 2, 2020 · In Python numpy.dot () method is used to calculate the dot product between two arrays. Example 1 : Matrix multiplication of 2 square matrices. Output : [26 31]] Example 2 : Matrix multiplication of 2 rectangular matrices. Output : [26 31 8] [46 55 14]]
Python Program to Multiply Two Matrices
Here are a couple of ways to implement matrix multiplication in Python. [4 ,5,6], [7 ,8,9]] # 3x4 matrix . [6,7,3,0], [4,5,9,1]] # result is 3x4 . [0,0,0,0], [0,0,0,0]] # iterate through rows of X for i in range(len(X)): # iterate through columns of Y for j in range(len(Y[0])): # iterate through rows of Y for k in range(len(Y)):
Matrix Multiplication in Python (with and without Numpy)
Matrix multiplication, also known as matrix dot product, is a binary operation that takes a pair of matrices and produces another matrix. In Python, this operation can be performed using the NumPy library, which provides a function called dot for matrix multiplication.
