应用背景随着物理科学所研究的现象在广度和深度两方面的扩展，偏微分方程的应用范围更广泛。这里给出典型抛物型、椭圆型、双曲型偏微分方程的程序代码，可供刚刚接触偏微分方程的人学习参考使用。关键技术具体内容包括：抛物型方程的显示格式、隐式格式（Crank-Nicolson）解法；二阶线性双曲型方程的显示格式、隐式格式解法、精确解；椭圆型方程的Jacobi迭代解法和精确解。

很多工程应用中labview一位数组排序非常简单，但是二维数组排序却很费脑筋，作者以前调项目写的小饭粒拿来分享分享

       Dual Tone Multi Frequencies (DTMF tones) are two different tones at two ends of a spectrum that are used to send information in telephonic communication mediums. The tones represent numbers 0-9 and the symbols * and #. A series of these numbers may be assigned to individuals as points of contact, as in a phone number, or the numbers can be used to relay other sorts of information.       While it may seem confusing, it should be noted that all numbers on a telephone are assigned two DTMF tones, and in all, seven different frequencies are assigned. Some numbers will have the same lower frequency, but different higher frequency, while others will have the same higher frequency but a different lower frequency. The range is between 697 Hz and 941 Hz for the lower frequencies and 1209 Hz and 1633 Hz for

c++实现基础的图像处理，适合各种图片的镜像处理，有详细的注释，并提供测试图片，运行良好，适合c++学习者

此矩阵用高斯消元法求二元域矩阵H的逆矩阵，此算法不需要H时满秩矩阵，对于满秩矩阵，H的逆矩阵G为[P,I]，对于不满足矩阵，P的最后列为全零列，本算法适合刚进入编码领域的人，不知如何求生成矩阵，特别是当生成矩阵的为非满秩矩阵的时候可用。

OFELI is an object oriented library of C++ classes for development of finite element codes. Its main features are : * Various storage schemes of matrices (dense, sparse, skyline). * Direct methods of solution of linear systems of equations as well as various combinations of iterative solvers and preconditioners. * Shape functions of most "popular" finite elements * Element arrays of most popular problems (Heat Transfer, Fluid Flow, Solid Mechanics, Electromagnetics, ...).-OFELI is an object oriented library of C++ classes for development of finite element codes.
