Gauss-Seidel methodThe Newton-Raphson procedure is designed to solve an equation of the form f(x) = 0. It starts with a guess of the solution: x = x 0 . It then produces successively better estimates of the solution: x = x 1 , x = x 2 , x = x 3 , ...using the formula ...
(1.44) to an iterative formula: (1.45)xn+1=xn−f(xn)f'(xn) In contrast to the method of linear interpolation, the Newton-Raphson method uses the newly found position as the starting point for each subsequent iteration. In the discussion for both linear interpolation and Newton-Raphson ...
1 Newton-Raphson Method To?nd a value of x that satis?es the equation f(x)=0,(1) where f(x)is some function,the Newton-Raphson method uses the following formula to get a better estimate of x from a previous value of x. x n+1=x n?f(x n) f (x n) .(2) where x n+1is...
Keywords:gas-liquidequilibrium;Wilsonequation;Newton-Raphsonmethod 然而,Wilson方程也有其不足之处,如它的参数不 易被关联,因此,求解的方法大都采用直接迭代方法和 线性化方法。本文以水和乙醇二元体系的气液平衡数据 为例,利用Newton-Raphson法拟合Wilson方程的参数。 Newton-Raphson法是一种求解非线性方程十分有效的...
