MATLAB

matlab 源程序，很好，推荐下载！很实用！！在项目中可能会用到(matlab source code, very good, recommended download! Very practical! ! In the project may be used)

一个计算齿轮过渡曲线的MATLAB程序，对初学齿轮的朋友非常有用(Calculation of the transition curve of a gear MATLAB procedures, useful for beginners gear Friends)

SIGMA DELTA MODULATOR

利用MATLAB 计算调制传递函数，在已知波前时，求解调制传递函数。( Purpose: Calculate and Plot MTF of the Wave Aberration Function This file calculates and plots the MTF of the Wave Aberration function specified by: jmax = highest mode in Wave Aberration Expansion Wrmsj = rms Wave Aberration coefficients of modes 0 to jmax d = pupil diameter in mm lambda = wavelength in nm )

模拟大学物理干涉现象，单色光和多色光都有，现象明显。(Analog University physical interference phenomenon, monochromatic and polychromatic light has obvious.)

该Matlab程序给出了Schmidt-Kalman filter和标准Kalman filter之间的性能对比，不是函数的形式，是直接的可执行程序，如有需要，直接更改文件中的参数就可以了(The Matlab program gives the Schmidt-Kalman filter and standards of performance comparison between the Kalman filter is not a function of the form is directly executable program, if necessary, change the file directly to the parameters can be a)

Simulation program to realize DS-CDMA system

实现随机信号序列的QPSK调制和相干解调，观察信号的星座图，计算误比特率和误码率。(this code is designed for the signal s QPSK modulation and demodulation exactly. Meanwhile, the BER and SER were estimated and drawed.)

Convert from latitude, longitude, and altitude (geodetic with respect to the WGS-84 ellipsoid) to a position vector in the Earth-centered, Earth-fixed (ECEF reference frame.

bessel函数求零点，给一个参数x,则可以求出x附近的bessel函数的零点。(bessel function of order zero, to a parameter x, you can find the bessel function of x near zero.)
