 利用fft()进行快速傅立叶变换，得到频谱，画出正弦函数及其频谱  找出频谱中使得Y轴取最大值时的估计频率记为ft  加入白噪声，绘出信噪比和均方误差的关系曲线 ( using fft () for fast Fourier transformation, spectrum, to draw the sine function and its spectrum  find the spectrum makes the Y-axis maximum value when the estimated frequency is denoted by ft  adding white noise, SNR plot and mean square error curve)

一些介绍，关于mathematica程序的应用说明。(some program about mathematica 10)

加权l1-极小恢复k块稀疏信号恢复，加的权重是多个，并且不相等。(Sparse signals recovered by the weighted l1-minination.)

by using this code , you have to get the LBPH of an face input .

本文通过对当前实时控制的应用研究，提出了将离线仿真与实时控制有机结 合起来，利用MATLAB实现对直线单级倒立摆实时控制的思路。经过分析比较， 确定了基于MATLAB的Real-Time Windows Target实时内核开发硬件驱动程序 的实时控制方案，将Simulink生成的仿真模型下载到目标实时内核中运行，驱动 外部硬件设备，实现对倒立摆的控制。文中介绍的在Real-Time Windows Target 实时内核环境中开发第三方设备驱动程序的方法，是构建本实验平台的核心技术 之一，具有普遍适用性，有一定的推广价值。(Based on the current real-time control of the applied research, raised offline simulation and real-time control organically combined to realize the use of MATLAB linear single-stage inverted pendulum idea of real-time control. After analysis and comparison, to determine based on MATLAB)
