普通PID控制及其扩展算法控制的MATALB仿真程序，内容包含面广．(ordinary PID control algorithm and its expansion of enriching control simulation program, which includes many sectors.)

说明：  This code for shift factor problems

hystersis control algorith which is bein done in matlab

说明：   已知过热蒸汽压力和焓，查询过热蒸汽温度的函数。(Known pressure and enthalpy of superheated steam, superheated steam inquiries a function of temperature.)

用matlab仿真的离散信号的频域实验分析(Experimental analysis of the frequency domain of the discrete signal simulation using matlab)

svm多种分类的核函数。可以实现，简单好用。(Kernel svm multiple classification. Can be achieved, easy to use)

建立模型-处理光照图像,特别是线性光照条件下的图像处理(Modeling- light image processing, especially under the conditions of the linear light image processing)

This code is used for find the Spectral magnitude error....and Spectral phase error....

其实popupwindow用起来比Dialog 方便，因为dialog一切都需要你自己来实现，而popupwindow帮我们实现了很多，我认为在使用的时候关键我们要看清参数： popupWindow.showAtLocation(parent, gravity, x, y) parent这个是一个父view试图， gravity 这个默认是居中，我们要指定显示方式：Gravity.LEFT | Gravity.TOP 最后两个参数就是显示的坐标位置，这样就可以根据需求自己定位显示位置了

ift codes to help others....,
