Challenge: Solving the Task Using SLE
Task
Swipe to show code editor
We have already considered how to solve the SLE using inversed matrix. But we can also use np.linalg.solve(A, y) method that calculates the solution of the SLE:
A * x = y.
Your task is to solve the system using both these methods and compare the results:
- Use
np.linalg.solve()method. - Use
np.inv()method to calculate inversed matrix and provide solution using:x = A_inv @ y.
