自己编的matlab厂程序。这是将局部坐标系的坐标转化为球面坐标系的坐标，非常实用。(own addendum to the Matlab plant procedures. This is the will of local coordinates into spherical coordinates, very practical.)

多项式拟合函数，用于给定数据点的多项式拟合，区别于matlab内置的函数polyfit,但效果差别不大。(A simple way of polynomial fitting to given points ,which is different from polyfit function but with no much different in result .)

大地电磁二维正演程序是电磁法的基础编程，首先设置地电断面然后通过正演模拟电磁场在大地中的传播形式来得到地下地质体的电阻率情况，从而得到地下地质体情况(Two-dimensional magnetotelluric forward modeling procedure is based programming electromagnetic method, first set the geoelectric section and then through the forward modeling electromagnetic propagation in the earth in the form to get the subsurface resistivity body condition, resulting in underground geological conditions)

通过MATLAB工具箱运用离散傅里叶变换对正弦信号和放波信号进行傅里叶分析(Through the use of Discrete Fourier Transform MATLAB toolbox on the sine wave signal and let the Fourier analysis of signals)

一份大学本科DSP的课程课设，包括源码还有说明(This is a rar file,including source code and filter design.Besides,some profile on the file.)

用MATLAB实现模糊控制算法，对如何进行模糊控制仿真很有帮助！！！(Using MATLAB implementation of fuzzy control algorithm, fuzzy control on how to carry out simulation helpful! ! !)

本代码对OFDM中载波频偏对系统误码率的影响进行了全面的仿真和比较，对加深对OFDM载波同步技术的理解很有帮助(The code in OFDM carrier frequency offset the impact of the system bit error rate of a comprehensive simulation and comparison to deepen the understanding of OFDM carrier synchronization helpful)

Matlab简单模拟双缝衍射的平面光强分布及一维光强分布(Matlab simulation of the intensity distribution simple double-slit diffraction plane and the one-dimensional intensity distribution)

步进电机失步情况的一个仿真.这是一个比较完整的方针,但是仅仅考虑了在单个脉冲下的失步情况.(Stepper motor out-of-step situation in a simulation. This is a relatively comprehensive approach, but considered only in a single pulse under the out-of-step situation.)

采用EM，期望最大方法，估计QPSK调制方式下的信噪比(Using EM, expectation maximization method to estimate the signal to noise ratio under QPSK modulation)
