说明：  想必大家对星空极速痛恨有加,至于危害也不必多说,下面的方法100 有效,而且不限地区,全国通用.解除后可以用XP自代程序拨号,可多机上网. (Everyone must have hated the Star has added speed, as to harm do not have to say, the following method 100 effective, but not limited to, regional, national general. The lifting procedure can be used XP since the generation of dial-up, can be multi-machine online.)

包括IHS遥感图像融合算法，比较全。基于MATLAB。(IHS image merging)

北京大学控制类计算机辅助设计的课件及课堂实例程序(Beijing to control the type of computer-aided design software and examples of classroom procedures)

数字信号处理实验内容，编写能够实现fft的matlab程序，并与系统自带的fft相比较。在文件mysecond.m中注释部分给出多种fft实现方法及代码，未拆分成多个m文件(Digital signal processing experiment content, the preparation can be achieved fft matlab program, and compared with the system comes with the fft. The comment section file mysecond.m give multiple fft to achieve method and code into multiple m 未拆)

INTDUMP Integrate and dump. Y = INTDUMP(X, NSAMP) integrates the signal X for 1 symbol period, then outputs one value into Y. NSAMP is the number of samples per symbol. For two-dimensional signals, the function treats each column as 1 channel.

说明：  利用AR模型仿真瑞利衰落信道，可用为信道建模做参考(Program to simulate Rayleigh fading using a p-th order autoregressive model AR(p) )

contrast adjusment Contrast is the difference in luminance or color that makes an object (or its representation in an image or display) distinguishable. In visual perception of the real world, contrast is determined by the difference in the color and brightness of the object and other objects within the same field of view. Because the human visual system is more sensitive to contrast than absolute luminance, we can perceive the world similarly regardless of the huge changes in illumination over the day or place to place. The maximum contrast of an image is the contrast ratio or dynamic range
