WebWe use numpy.linalg.inv () function to calculate the inverse of a matrix. The inverse of a matrix is such that if it is multiplied by the original matrix, it results in identity matrix. Example import numpy as np x = np.array( [ [1,2], [3,4]]) y = np.linalg.inv(x) print x print y print np.dot(x,y) It should produce the following output − Webwhich is its inverse. You can verify the result using the numpy.allclose() function. Since the resulting inverse matrix is a $3 \times 3$ matrix, we use the numpy.eye() function to …
