说明：  自己搭建的matlab电机仿真中的SVPWM模块，其中U_alpha,U_beta为电压输入，T为开关周期，U_dc为直流母线电压，PWM为六路脉冲信号，绝对好用(Matlab built their own motor simulation SVPWM module, which U_alpha, U_beta the voltage input, T is the switching cycle, U_dc for the DC bus voltage, PWM pulse signal for the six-way, absolutely easy to use )

实现语音断点检测的程序，有静音处理和噪声去除，已编译通过。(Voice breakpoint detection program, mute processing and noise removal, compiled by.)

这是光学激光仿真相关书籍的源代码，里面有全面的关于激光器以及介质仿真的基本代码，这是第三部分的内容，总共有6个部分。(This is the simulation of the optical laser source code related books, which has comprehensive information regarding the lasers and media simulation of the basic code, which is the third part of the content, a total of six sections.)

说明：  介绍了非线性姿态的滤波方法，加性ekf以及乘性ekf等(Introduction of non-linear profile filtering method, the additive and multiplicative EKF EKF, etc.)

说明：  采用离散再合成的随机流动生成(DSRFG)方法合成了满足目标湍流度、积分尺度、脉动风速谱及空间相关性等参数的各向异性湍流;讨论了DSRFG方法在生成湍流风场上关键参数的合理取值;(Anisotropic turbulences satisfying the parameters of target turbulence, integral scale, pulsating wind speed spectrum and spatial correlation are synthesized by discrete resynthesis random flow generation (DSRFG) method. The key parameters of DSRFG method in generating turbulent wind field are discussed. Reasonable value;)

this is basic for understood radar

dijkstra算法的matlab实现，验证数据采用了河北省主要城市的赋值无权网络图，并分析了单程往复式行驶的效率因素，实际应用价值高(the dijkstra algorithm matlab to achieve, verify the data used in major cities in Hebei Province network has no right of assignment, and an analysis of the efficiency of one-way reciprocating driving factors, the practical application of high value)

here to import the pictures and how to segment the picture. how to add the noise. some screen shots will be added this file.
