一些关于数学思想应用的matlab代码，以供大家学习分享；(The application of mathematical ideas about matlab code for them to learn to share )

copula工具箱，可以进行copula计算，比自带的更加好用(copula toolbox)

说明：  三维FMM射线追踪程序，计算得到核矩阵 时间场(Three - dimensional ray tracing program, the calculation of the kernel matrix)

说明：  分维反映了复杂形体占有空间的有效性，它是复杂形体不规则性的量度。它与动力系统的混沌理论交叉结合，相辅相成。它承认世界的局部可能在一定条件下或过程中，在某一方面（形态，结构，信息，功能，时间，能量等）表现出与整体的相似性，它承认空间维数的变化既可以是离散的也可以是连续的，进而拓展了视野。(Fractal dimension reflects the validity of space occupied by complex bodies, which is a measure of irregularity of complex bodies. It combines with chaos theory of dynamic system and complements each other. It recognizes that the part of the world may be similar to the whole in certain conditions or processes (form, structure, information, function, time, energy, etc.). It recognizes that the change of spatial dimension can be discrete or continuous, thus expanding the horizon.)

说明：  三角形网格上的线性有限元方法求解Helmholtz问题，多项式重构以及Richardson外推(solve the Helmholtz equation with robin boundary condition on triangulation mesh, PPR and Richardson extrapolation)

用SVD奇异值分解法和阻尼最小二乘算法解决地球物理反问题，程序比较简单易懂(Using SVD, singular value decomposition method and damped least-squares algorithm to solve geophysical inverse problem, the procedure is relatively simple to understand)

用C++来实现NEWTON迭代法解非线性方程算法数值分析，是数值分析里典型的一个算法。(In C++ to achieve NEWTON iterative numerical algorithm for solving nonlinear equations, numerical analysis is in a typical algorithm.)

最小二乘法和支持向量回归机相结合无线传感网络节点定位的源码.(The source of The least squares and support vector regression combining wireless sensor network node positioning . )

这是一个数值计算Fortran程序，将矩阵进行奇异值分解，SVD.txt存放待分解的矩阵，u.dat,v.dat为分解后的左右矩阵，qiyizhi.dat和qiyizhi0.dat为得到的奇异值。(This is a numerical Fortran program matrix singular value decomposition, SVD.txt store to be factored matrix, u.dat, v.dat about decomposition of the matrix, qiyizhi.dat and singular value obtained qiyizhi0.dat .)
