一维fdtd程序，自由空间，调制高斯脉冲波源(1 dimensional fdtd program)

image为待做锐化的图像 imagegoal为锐化后的图像">

说明：  使用抖动创建图像。使用抖动得到的图像看上去有更多的颜色数；不适用抖动得到的图像看上去颜色数少，大门空间分辨率要高些。(Creating images using dithering. Jitter by using the image appears to have more number of colors not apply to jitter resulting image looks small number of colors, the door to higher spatial resolution.)

matlab仿真对采集数据进行滤波的两种方法：多次平均滤波和一阶滞后滤波的比较。(matlab simulation filtering the collected data in two ways: the average number of first order lag filter and the filter comparison.)

现代信号处理 一个序列为 ，使用FFT分析其频谱： 1） 使用不同宽度的矩形窗截短该序列为M点长度，取M分别为： a) M=20 b) M=40 c)M=160 ；观察不同长度的窗对谱分析结果的影响； 2）使用汉宁窗、哈明窗重做1） 3）对三种窗的结果进行理论分析及比较。并绘出相应的幅频特性曲线 (Modern signal processing a sequence, using FFT analysis of the spectrum: 1) the width of the rectangular windows with different truncated point of the sequence length of M, take M, respectively: a) M = 20 b) M = 40 c) M = 160 observation windows of different lengths affect the results of spectral analysis 2) Hanning window, Hamming window redo 1) 3) the results of three windows and compare the theoretical analysis. And draw the corresponding amplitude-frequency characteristic curve)

henon 分岔图与相图的绘制。能够得出各种条件下的相图与分岔图，并进行分析。(henon bifurcation diagram and phase diagram drawing. Able to draw the phase diagram of various conditions and bifurcation diagram, and analyzed.)

this is a basic sff code about SML METHOD.

说明：  图象压缩方面的论文pdf格式 可用于毕业设计方面的工作(Image compression pdf format papers for school design work)

matlab仿真,超宽带信号中,产生固定周期数的正玄信号(matlab simulation, ultra-wideband signal to produce a fixed number of periods is mysterious signal)

电子书，LabVIEW与Matlab混合编程，很好的东东。(E-book, LabVIEW and Matlab mixed programming, good Dongdong.)
