汽车加油问题的算法-vehicle refueling the algorithm

工程计算中，很多时候都会用到矩阵的运算，很多时候必然会涉及到矩阵的求逆，我提供了一个矩阵求逆的算法，可以用实际的矩阵验证程序的正确性。

应用背景JPHide 和JPSeek 的源代码！JPHide&JPSeek是一个JPEG图像的信息隐藏软件！-JPHide and JPSeek source code! JPHide & JPSeek is a JPEG image information hidden software!关键技术JPHIDE and JPSEEK are programs which allow you to hide a file in a jpeg visual image. There are lots of versions of similar programs available on the internet but JPHIDE and JPSEEK are rather special. The design objective was not simply to hide a file but rather to do this in such a way that it is impossible to prove that the host file contains a hidden file. Given a typical visual image, a low insertion rate (under 5%) and the absence of the original file, it is not possible to conclude with any worthwhile certainty that the host file contains inserted data. As the insertion percentage increases the statistical nature of the jpeg coefficients differs from "normal" to the extent that it raises suspicion. Above 15% the e

关于多次样条插值的经典算法-on several spline interpolation algorithm classic

这是一个对语音信号(0.3kHz~3.4kHz)进行低通滤波的C语言程序， 低通滤波的截止频率为800Hz，滤波器采用19点的有限冲击响应FIR滤波。 语音信号的采样频率为8kHz，每个语音样值按16位整型数存放在insp.dat文件中。-This c program is a low pass filter for radio signal 0.3kHz-3.4kHz.The stop frequence of this filter is 800hz.This digtal filter chooses 19 points FIR.the fs is 8kHz.every datas is memoryed in filed-insp.dat.

用sobel算子实现边缘检测源代码，用C++实现了sobel算子。图像编码完整实现。

计算方法上机列主消元-calculation on the plane out the main elimination

关于小波的matlab四种变换，研究小波应用的很需要-on four Matlab wavelet transform, the application of wavelet research is needed

应用背景这是我整理的三次样条插值的算法，算法比较简单，希望大家能用得到，如果，有问题，大家可以好好看一下里面的代码结构，只要仔细看，问题应该都不大的。如果实在不行，就翻翻课本。关键技术 利用FORTRAN编制的三次样条插值，如果三次样条大家都很清楚，我就不用多说了，是行家都懂，如果实在不懂，那就没有下载的必要了。而且程序也相对简单一些。希望能用心好好看。
