Answer:
hope this help and do consider giving brainliest
Explanation:
1)
a)
import numpy as np
A=np.array([[1,4,3,2],[1,7,4,5],[2,5,3,1],[1,3,2,9]]);
print("Inverse is");
B=np.linalg.inv(A);
print(B);
print("A*A^-1=");
print(np.dot(A,B));
print("A^-1*A=");
print(np.dot(B,A));
2)
import numpy as np
A=np.array([[4,3,2],[5,6,3],[3,5,2]]);
B=np.array([[3,-1,2,6],[7,4,1,5],[5,2,4,1]]);
X=np.dot(np.linalg.inv(A),B);
print("X=");
print(X);
