Broyden algorithm

In numerical analysis, Broyden's method is a quasi-Newton method for finding roots in k variables. It was originally described by C. G. Broyden in 1965. Newton's method for solving f(x) = 0 uses the Jacobian matrix, J, at every iteration. However, computing this Jacobian is a difficult and expensive operation. … See more Solving single-variable equation In the secant method, we replace the first derivative f′ at xn with the finite-difference approximation: and proceed similar to See more • Dennis, J.
