怎样Coding Like a Pro?用MATLAB实现一个Newton-Raphson求解器(一) 拉夫森迭代法是求解非线性方程的常用方法,其实现简单,除了某些特殊情形,收敛速度很快,在工业界使用也是相当广泛。倘若我们自己想实现一个一个求解器,该如何实现呢? 这里假设你对算法的原理已经有基础的认识了,如果没有,你可以参考任何一门介绍数值计...
怎样Coding Like a Pro?用MATLAB实现一个Newton-Raphson求解器(二) 有了上一期的经验,一切似乎都毫无压力,但仔细一想,前面的简单算法似乎麻烦了一些。 它不光要求解方程的时候给出函数方程本身,还要给出函数的导函数。 而且,不光是麻烦,万一使用函数的人给出了一个错误的导函数,那问题就大了。。 所以,解决方案...

In this paper, model predictive control algorithm drives the positioning control of DC motor and neural network using Newton-Raphson method trains the data in an orderly fashion to achieve desired output. Model predictive control tests the functioning of required position enabling DC motor operation ...
The next stop condition checks to see if the change in all the new beta values is smaller than some small value of parameter epsilon, using helper method NoChange. This indicates that Newton-Raphson has converged and, in fact, there’s a good chance your model is now over-fitted. Instead...

First of all, you never evaluate f to start the method out. Yes, since you know the function f AND the starting value, f(1) = -1, so your code looks like it will work since you hard coded f initially as -1, but it is poor coding style anyway.
For the reciprocal unit the divider uses Newton Raphson method and for multiplication unit it uses the multiplication operator. The Verilog HDL coding of the proposed divider design is simulated using Xilinx Vivado tool and synthesized using Cadence EDA tool....
In this section, we introduce the two-step fractional Newton–Raphson method (TSFNRM), which is a modified version of the Newton–Raphson technique. Now, the following result demonstrates the convergence analysis of Algorithm 1. Algorithm 1 Two-step Caputo-Fractional Newton–Raphson Method (TSFNR...
