这是我毕设做自动调焦仿真实验时，编写的自动调焦函数的Matlab代码，把基于灰度梯度的调焦函数都仿真了(This is what I do complete auto-focus based simulation experiments, the preparation of the automatic focusing function of the Matlab code, the gray gradient-based simulation of the focusing functions)

恒模算法仿真，该算法是Bussgang算法的特例，是一种工程应用非常广的算法。(constant modulus algorithm simulation, the algorithm is a special case Bussgang algorithm, Application is a very broad algorithm.)

In MATLAB, usually we use function bvp4c() to solve boundary value problem (BVP) of ODE. However, we also can use function ode45() to solve BVP of ODE too. However, ode45() needs all initial values at one point. Therefore we have to construct an auxiliary function, whose input argument is the missing initial value and the return output is the given boundary value, Then we can call function fsolve() to get the missing initial value. This method is particularly efficient it the ODE has one or more parameters. Also this method is essentilal for GNU Octave, because whose function bvp4c() is not programmed for parameter ODE yet.

本程序实现了一个简单的非线性约束最优化问题，仅供参考(This program implements a simple nonlinear constrained optimization problems, for reference only)
