对sgy格式的地震数据，进行各种操作。包括读取和制作，以及道头字提取，地震数据提取等。期待与有共同目标的朋友们研究。(Sgy format for seismic data in the various operations. Including the reading and production, as well as the Road, the first word extraction, data extraction, such as an earthquake. Look forward to working with common goals have friends study.)

DSP course Tut1-_Intro

Its a great tool to getting started with the new John Carter software for source code.

k-means 算法，可以实现数据的分类输出(k-means 算法，可以实现数据的分类)

负折射率光子晶体的带隙计算程序请大家参考(Negative refractive index photonic crystal band-gap calculation procedures please refer to)

通过寻找Z变换矩阵，对给定矩阵进行降相关运算。相关专业的朋友懂的。(By finding the transformation matrix Z, given the lower correlation matrix operations. Relevant professional friends understand.)

说明：  本代码为经典PSO微粒群算法，通过修改w值，使得PSO的搜索在全局与局部之间得到最优(The code for the classic PSO particle swarm algorithm, by modifying the w value, makes the PSO search between the global and local optimal)

三相逆变器空间矢量控制源程序，SIMULINK仿真结果显示，能够完美得到指定信号。(Three-phase inverter space vector control program SIMULINK simulation results show that perfectly specified signal.)

Physicalsimulations in Matlab

This paper presents digital simulation of ZVS half bridge DC to DC converter with modified PWM control. The switching losses are reduced by using soft switching. Conventional and duty cycle shifted PWM DC to DC converters are simulated using matlab simulink and the results are presented. The principle of operation and the key features of modified PWM DC to DC converter are also presented.
