'''12. Orthogonal Matrix'''
'''This example will show that the following matrix is not orthogonal '''
Code Starts Here
==============
import numpy as np
matrix = np.random.randint(0,9,(4,4))
print(matrix)
matrix_transpose = matrix.T
print(matrix_transpose)
print(matrix.dot(matrix_transpose))
This example will show the matrix is orthogonal for unit matrix
umatrix = np.eye(4,4)
print(umatrix)
matrix_transpose=umatrix.T
print(matrix_transpose)
print(umatrix.dot(matrix_transpose))
Show that matrix is orthognal for non unit matrix
from scipy.stats import ortho_group
m = ortho_group.rvs(dim=4)
print(m)
np.set_printoptions(suppress=True)
print(m.dot(m.T))
print(m.T)
print(np.linalg.inv(m))
13. Singular Matrix
This will show that determinant is non-zero and hence not singular
import numpy as np
matrix = np.random.randint(0,9,(4,4))
print(matrix)
print(np.linalg.det(matrix.T.dot(matrix)))
This will show that determinant is zero and hence singular
matrix = np.eye(3,3)
matrix1 = np.ones((3,4))
matrix1[:,:-1] = matrix
np.linalg.det(matrix1.T.dot(matrix1))
matrix = np.zeros(shape=(10,10))
print(matrix)
