Fsolve system of equations python
WebSolve the system of equations x0 + 2 * x1 = 1 and 3 * x0 + 5 * x1 = 2: >>> a = np.array( [ [1, 2], [3, 5]]) >>> b = np.array( [1, 2]) >>> x = np.linalg.solve(a, b) >>> x array ( [-1., 1.]) Check that the solution is correct: >>> np.allclose(np.dot(a, x), b) True WebThe f_solve function takes in many arguments that you can find in the documentation, but the most important two is the function you want to find the root, and the initial guess. TRY IT! Compute the root of the function f ( x) = x 3 − 100 x 2 − x + 100 using f_solve. from scipy.optimize import fsolve
