说明：  matlab开发个人桌面日历，纯为matlab更好的学习，和个人兴趣的培养。熟悉matlab语法规则。(development of personal desktop calendar matlab, matlab better purely for learning, training and personal interests. Familiar with the matlab syntax rules.)

地震数据SEGY的读写，使用matlab，简单易用。(seismic data SEGY s reading and writing)

IDL转Matlab，可以将IDL源代码转成MATLAB，并有例子(IDL to Matlab)

用MATLAB实现AsyLnCPSO算法，程序没错误，可以直接运行，非常适合刚学PSO者(Implementation of AsyLnCPSO algorithm with MATLAB, the program no error, can be directly run, very suitable for just learning PSO )

Differential PSK (DPSK) 􀂄 Inexpensive 􀂄 Quadrature Phase Shift Keying (QPSK) 􀂄 Twice as spectrally efficient than BPSK 􀂄 Offset QPSK (OQPSK) 􀂄 reduce envelope variation 􀂄 π/4 QPSK 􀂄 reduces envelope variations to a lesser extent than OQPSK can be noncoherently detected

说明：  国家雷达重点实验室，廖老师的课件，值得大家学习。(National radar Key Laboratory, teacher Liao's courseware, is worth learning.)

This is the parser of NMEA encoded data from GPS it separates lat and long

异步电机解耦矢量控制系统的数字控制器设计,先求解出解耦以后的异步电机矢量控制方程，然后将其离散化，在此基础上设计了数字控制器，文件中包含相关的Simulink仿真模型和Word说明。(Decoupled induction motor vector control system digital controller design, the first decoupling solved after induction motor vector control equations, then discretized on the basis of the design of the digital controller, the file contains the relevant Simulink simulation model and Word instructions.)

利用 MATLAB 实现窗函数法设计 FIR 滤波器，主要是选择合适的窗函 数进行截断运算 (Window function method using MATLAB to design FIR filter, main is to choose the appropriate letter for window blocking operations.First theoretically to approximate the unit impulse response of ideal filter hd [k], to be determined by the passband and stopband attenuation index window function types, determined by transition zone FIR filter order M length (or N), and finally USES MATLAB to calculate the window function value, and hd wN [k] [k] value, so that the design of FIR filter h (k) MATLAB provides the blackman window function is: w = blackman (N) Where N is the length of the window function.)
