椭圆滤波器C程序和matlab的仿真m文件，根据matlab仿真设计椭圆滤波器参数，再编写C程序(C program of ellipsefilter)

运用matlab软件，编程运算，进行回归分析(Use matlab software, programming operations, the regression analysis)

说明：  协同过滤算法matlab代码,算法本身挺简单的，建议你自己试着编一下(Collaborative filtering algorithm matlab code )

利用幂法和反幂法求解按模最小特征值，按模最大特征值。与MATLAB中eig功能相似 (get the character value of a matrix, similiar with the function eig in matlab)

读入指定的音频序列，并对其进行无损预测编码和DM调制编码(Read into the specified audio sequences, and its lossless predictive coding and modulation coding DM)

不用说的好，我们室主任开发的Photonics cyrestal band gap计算Fortran代码。注意不要忘了input文本。(Needless to say the good, our director of development Photonics cyrestal band gap calculation of Fortran code. Do not forget to pay attention to input text.)

常胜将军 :在计算机后走的情况下，要想使计算机成为“常胜将军”，必须找出取 关键。根据本题的要求枷以总结出，后走一方取子的数量与对方刚才一步取子的数量之和等于，就可以保证最后一个子是留给先取子的那个人的。(Ever Victorious General: On the computer where to go, in order to make the computer become " Ever Victorious generals" must be taken to find the key. According to the requirements of this title thoughts to conclude that one party to take the child away after the number of step with each other just to take the child and is equal to the quantity, we can ensure that a child is left to the first final to take the child of that individual.)

matlab 的程序求解三对角方程组,三对角方程组中的系数矩阵是非奇异的，这是前提条件。(matlab program for solving tridiagonal equations, tridiagonal equations nonsingular coefficient matrix, which is a prerequisite.)
