带约束算子的粒子群算法，用于matlab环境，对于搞研究的教师有很大帮助-Operator Constrained Particle Swarm Optimization for the matlab environment, engage in research for teachers are very helpful.

copulafit 和 t-copulafit 用matlab编写的copulafit函数来拟合相应的数据以及常用的t-copulafit来拟合相应的数据 -copulafit and t-copulafit RHOHAT = copulafit( Gaussian ,U) [RHOHAT,nuhat] = copulafit( t ,U) [RHOHAT,nuhat,nuci] = copulafit( t ,U)

MATLAB小程序，COPULA函数对计算多元统计量的联合概率密度！-MATLAB small programme, which is used to calculate the Copula Function.

Copulafit是一种集成多组数据，求出联合分布的函数，在金融风险度量中有广泛应用。-Copulafit is an integrated set of data, find the joint distribution function, there is a wide range of applications in financial risk metrics.
