灰色预测 GM（1,1）在数据量较少的情况下进行的灰色预测 (Grey GM (1,1) in the case of small amount of data for the Grey)

Nonuniform mesh semivector: Illustrates usage of the semivector modesolver to calculate the quasi-TE and quasi-TM modes of a ridge waveguide. Use the stretchmesh function to expand the size of the computation window at the edges without increasing the number of gridpoints.

基于matlab开放的贝叶斯统计软件包，可以进行多种贝叶斯统计(Based on Bayesian statistical package matlab open, can be a variety of Bayesian statistics)

model of boost in Matlab

本程序基于Matlab，可以对特定波长光线在透镜系统中进行光线追迹。可以生成任意方向平行光，点光源任意角度光线，并对全反射，光线射出系统等特殊情况用红色标出。透镜数任意，透镜参数可设。(The program is based on Matlab, with a specific wavelength of light in the lens system for ray tracing. Parallel light can be generated in any direction, at any angle point source of light, and the reflection of light injection system and other special circumstances marked in red. Any number of lenses, lens parameters can be set.)

a matlab code to reduce the dimenision of data. using probability principle analysis
