Python Program to Multiply Matrices in NumPy import numpy as np # two dimensional arrays. In Python, the Scipy library can be used to convert the 2-D NumPy matrix into a Sparse matrix.SciPy 2-D sparse matrix package for numeric data is scipy. sparse .The scipy. sparse package provides different Classes to create the following types of Sparse. The numpy matrix is interpreted as an adjacency. We can implement this using NumPy's linalg module's matrix inverse function and matrix multiplication function. 1 beta_hat = np.linalg.inv (X_mat.T.dot (X_mat)).dot (X_mat.T).dot (Y) The variable beta_hat contains the estimates of the two parameters of the linear model and we computed with matrix multiplication. 1 2 print (beta_hat).
