无网格算法中的光滑粒子水动力学sph算法源程序（溃坝）(Meshless algorithm smoothed particle hydrodynamics sph algorithm source (dam))

全局牛顿-拉普森方法求解非线性方程组，自动搜索步长，进一步保证了程序的收敛(Global Newton-Raphson method for solving nonlinear equations. The steps can be found automatically. The convergence is better than the common Newton-raphson method.)

可以用最小二乘法来提取趋势项。在MATLAB中可利用它的函数来计算(Least squares method can be used to extract the trend items. It can be used in MATLAB to calculate the function)

说明：  球形粒子Mie 散射用Matlab编写的Mie theory计算程序。在光子学中运用广泛，使用非常方便(Mie scattering of spherical particles prepared by using Matlab program Mie theory. In the use of photonics in a wide range of very convenient to use)

说明：  用相场法模拟晶粒的长大的一个程序，用c++编写的，(a program simulation the grain growth by Phase field written using c++)

关于房屋贷款贷款的计算，包含本息、本金、一次性付款等贷款方式(Calculated on mortgage loans, including principal and interest, principal, and other one-time payment of loans)

说明：   这是几个常用的测试函数，通过这个测试函数可以比较算法性能的优劣。(This is a test of several commonly used functions, through this test function can compare the algorithm performance is good or bad.)
