Levenberg-Marquardt 算法的 Matlab 实现，附例子代码(Levenberg-Marquardt Algorithm implement in Matlab. )

在实际计算中，有时为了避免开方运算，或者要分解的矩阵只是对称而不是正定的，这时可以选用适合于一般对称阵的分解式(In the actual calculation, sometimes in order to avoid root operation, or just want to break down the matrix rather than positive definite symmetric, then you can choose suitable for general symmetric matrix factorization)

说明：  FIPSO算法，全信息粒子群算法，用于求解一些函数的最优值问题(fully informed particle swarm, a kind of particle swarm)

矩形导电平板，长为1厘米，宽为1.5厘米。22G－38G的宽带RCS矩量法求解(Rectangular conductive plate, 1 cm long, 1.5 cm wide. 22G-38G broadband RCS method of moments)

此程序用matlab完成了一个小功能，即完成对一个数据文件求最大值和索引！(This program completed with a small matlab function to complete the requirements for a data file and index the maximum!)

IYPT2014 第8题，matlab 模拟(IYPT2014 problem 8， matlab code)

用Matlab编写的三维荧光分析工具，可以导入、浏览荧光数据，自动进行平行因子分析，并确定荧光组分。(The drEEM toolbox (decomposition routines for Excitation Emission Matrices) has been developed to support and extend the application of PARAFAC to fluorescence Excitation Emission Matrix (EEM) datasets. The toolbox contains numerous MATLAB functions for importing, assembling and exporting datasets, applying spectral corrections, visualising EEMs, detecting sample outliers, and developing and validating PARAFAC models. drEEM uses the embedded N-way toolbox as its PARAFAC engine. )
