English Description：
Application backgroundMethod NewtonFirst The parameter FX is a external function with respect to viable X.Second parameter The DFX is the first order of function diffential fx.Is initial iteration point. x0 is a value for the solution.Is the tolerance of the loop. tolIs the maximum number of iterations. NKey TechnologyWhen using Newton method, it often includes two steps: the first step is to obtain approximate solutions with a global method (such as the drawing method); the second step is to obtain the exact solution with the accuracy required by Newton method. for example, the maximum value of y= (0.65-0.01*x) -0.45*x (0.025*x) 2*exp (x/40) x> /20 (200*exp) * (9*x) * () * (x 0) is obtained. F=0 - 2*exp (EXP) - (x/40 - 65) - (x -) - - /20 () - (x/40) - 9/20 (f) - () - () - () - () - () - f= () - result=newton1 (dfdx) - (19.5,0.000001,10), it is not easy to obtain analytical solutions.
