this programe is a simulation of OFDM using FFT

说明：  压缩包里包含了无约束优化问题常用的几种求解方法的源程序：变量轮换法（variable_rotation.m）、最速下降法（steepest_descent.m）、修正牛顿法（modified_newton.m）、共轭梯度法（conjugate_gradient.m）。另外，coefficient_matrix.m为目标函数系数获得矩阵，minval.m为最小值计算函数，gradient.m为梯度计算函数(Compression bag contains unconstrained optimization problems of several commonly used method of source: variable rotation Act (variable_rotation.m), steepest descent method (steepest_descent.m), as amended Newton (modified_newton.m), conjugate gradient method (conjugate_gradient.m). In addition, coefficient_matrix.m as the objective function coefficients obtained matrix, minval.m function for the minimum calculation, gradient.m for gradient calculation function)

extreme learning machine 例子 run satimage_mean(extreme learning machine examples run satimage_mean)

控制系统中pid控制的仿真模型，是simulink的模型的，希望对学习pid的同学有用。(control system pid control of the simulation model is the model of Simulink, pid hope that the right of students to learn useful.)

ADRC程序，实现自动调参,以及蒙特卡罗实验。(ADRC program to realize automatic parameter adjustment and Monte Carlo experiment.)

rls算法,实现含噪声信号的消噪，其噪声为高斯白噪声加入，绘制了滤波前后的波形图(rls algorithm to achieve denoising noisy signals, the noise is Gaussian white noise is added, drawing the waveforms before and after filtering)

很有用的关于VC和matlab混合编程的例子，值得大家学习(Very useful on the VC and matlab examples of hybrid programming, what is worth learning)

使用matlab编写程序控制摄像头获取外界图像(Use matlab program control camera image for the outside world)

This model were build to simulate flicker when switches the big load to the network. The result show that, when switches the load, voltage and current fluctuate and make flicker.
