说明：  matlab必备的源代码教程，希望能用的到(matlab)

The files explain aliasing , gibbs, dft and fft. All are very useful in signal processing applications and the files illustrate the contents very well with plots/graphs.

主成分分析法源码，可用于提取主成分，识别率百分之九十(the PCA code)

涵盖了一些基于小波变换的常见图像处理程序(Cover some common image based on wavelet transform processing)

电机拖动里的用空载点和负载点做出直流电机的固有机械特性曲线(failed to translate)

N 维电测深可视化正演窗口 可用于地下水平底层的情况 试错法正反演(N-dimensional visualization of electrical sounding the forward underground level of the bottom window can be used for the case of trial and error method and inverse)

用matlab编写的程序，关于MATLAB图像处理的边缘检测等等。(Matlab program, on matlab image processing, edge detection and so on )

说明：  作为具有高分辨以及成像功能的合成孔径雷达，已广泛被各国所研究。而RD算法却是成像领域最基础最最熟的基础算法。在此提供各大家，共同研究！(As well as a high-resolution synthetic aperture radar imaging, has been widely studied by various countries. The RD algorithm is most familiar image of the most basic of basic algorithms. Here are the people, to study!)

如何用Matlab画图 以西东方向为横轴，以南北方向为纵轴。（选适当的点为原点）将国土最西到最东边界在x轴上的区间划取足够多的分点xi，在每个分点处可测出南北边界点的对应坐标y1 ，y2，(How to use Matlab drawing XiDong direction in the north and south direction for the horizontal axis, for the vertical axis. (choose appropriate point for starting point the west to the east land border on the x axis of interval strokes on the locations take enough in every cent point place xi, can detect the north-south border points corresponding coordinates, y2 y1, )
