用来计算航天器再入质点弹道，其中包括插值算法，龙格库塔法以及大气模型(Used to calculate the particle trajectory of spacecraft re-entry, including the interpolation algorithm, Runge-Kutta method as well as atmospheric model)

是CA算法的test程序，用于描述微观枝晶长大的代码！(CA algorithm is the test procedure, used to describe the micro-dendrites grew up in the code!)

可以实现十几位整数的四则运算，效率也较好(Four operations can be more than a dozen integer,and the efficiency is better)

吉尔算法积分一阶微分方程组初值问题的C语言描述，包括主函数、计算微分方程组中各方程右端函数值的函数程序、计算雅克比矩阵的函数程序、矩阵求逆程序等。(GEAR algorithm integral first order differential equations initial value problem of the C language description, including the main function to calculate the differential equations in the equation right function value function procedures, functions Jacobian matrix calculation procedures, matrix inversion procedures.)

对于水轮机阀门开启、关闭的一瞬间，对于钢管有比较大的水击。该程序计算出了相对最大的水击压力。(For turbine valves opened, the closure of the moment, for a relatively large pipe water hammer. The program calculated the maximum relative pressure of water hammer.)

c++编写的小波包算法，可以实现小波包分解与重构，速度较快(A wavelet packet implementation written in C++, does wavepacket decomposition and reconstruction quite efficiently)

本算法是求取点到曲线的距离，希望对大家有帮助(the algorithm is to strike a point of the distance curve, and I hope to be helpful)

若矩阵A中的某一元素A[i，j]是第i行中的最小值，而又是第j列中的最大值，则称A[i，j]为矩阵A中的一个鞍点。请写出一个可确定此鞍点位置的算法（如果这个鞍点存在）。(If the matrix A, an element A [i, j] is the minimum value in the i-th row, but is the maximum value of the j-th column, then A [i, j] for the matrix A is a saddle point. Please write a algorithm to determine the position of saddle point (saddle point exists).)

C语言版,机载SAR回波仿真程序，附有FFT和复数库，以及位图显示模块。本程序注释详解，对加深SAR的理解有很好的帮助(C language version, airborne SAR echo simulation program with FFT and complex database, as well as bitmap display module. Detailed notes of this procedure, for deepening the understanding of SAR has a good assist)

QR分解法是目前求一般矩阵全部特征值的最有效并广泛应用的方法，一般矩阵先经过正交相似变化成为Hessenberg矩阵，然后再应用QR方法求特征值和特征向量。它是将矩阵分解成一个正规正交矩阵Q与上三角形矩阵R，所以称为QR分解法,(QR decomposition )
