数字图像处理之差影法源程序（初学者必备）(Digital image processing of subtraction method source (beginners necessary))

用MATLAB实现粒子群算法，实现MIMO信道均衡。(MATLAB particle swarm algorithm, realize the MIMO equalization.)

根据横波纵波的原理演示横波与纵波的形成过程(formation of transverse and longitudinal waves)

By using the ground points and image points in pervious work, we can calculate the six parameters of affine transformation. With these parameters, the ground coordinates can be transform in to image coordinates. In this homework, we compared (1) different terrain types with same GCP number. (2) Same terrain type with different GCP number. (3) Same terrain type with same GCP number but different distribution. Then, try to find out why the result will different. Keywords: Affine transformation, Ground control point.

绘制自旋航天器的相平面图形，改变参数可以绘制不同情况下的姿态(Draw spacecraft spin phase planar graph, changing the parameters can be plotted attitude under different circumstances)

基于K-means的模糊聚类分析方法，很有用的(Based on the fuzzy K-means cluster analysis, very useful)

This function transforms a three-phase unbalanced phasor into its symmetrical components. The Three phasors can be expressed in a one column array in rectangular complex form or in a two column array in polar form, with 1st column magnitude and 2nd column phase angle in degree. The function returns the symmetrical components in rectangular form. The function plots the original unbalanced phasors and the symmetrical components.

对加速度传感器采集的加速度数据进行二次积分，得出位移数据，并在几分过程中进行积分基线的标定，较精确。(The acceleration of acceleration sensors to collect data, a second integral part of displacement data, and in the process of integration, the more precise the baseline calibration.)

ofdm系统的源代码，非常有用。希望帮到大家(ofdm system source code, very useful. Hope to help everyone)

介绍了m 序列和Gold 序列的原理、性能和构造方法，接着在MATLAB 中用M 语言编程实现它们的产生和分析。(Describes the m-sequence and Gold sequence of principle, performance and construction methods, and then using M language in MATLAB programming their generation and analysis.)
