概率计算问题之前向算法

改进了BIHT l2 中的观测矩阵，实验结果证明，误差更小了(change BIHT l2 ，perform better)

此程序为计算桁架受荷载作用下的位移及应力算例(This program is subject to displacement and stress calculation truss under load examples)

FFT傅里叶快速变换，把变换的结果放到文件中，并用matlab绘制图形。( FFT the Fourier fast transformation, puts the transformation result to the document, and draws up the graph with matlab. )

基于simulink的直接频率合成器的实现，绝对好用(Simulink based on the realization of direct frequency synthesizer, absolutely easy to use)

txt格式，均为源码，带注解！共包括100个整。(txt format, all source code, with comments! A total of 100 whole.)

利用MATLAB环境编写的程序集和，用来对波导杆上的超声波传播进行模拟。(PCdisp (Pochhammer-Chree dispersion) is a small toolbox of Matlab routines which simulate numerically the generation and propagation of ultrasonic waves in a cylindrical waveguide. PCdisp can: Trace the dispersion curves (wavenumber-frequency) for all propagating and evanescent modes in the waveguide Find and plot the distribution of displacements and stresses of a mode in the waveguide Use modal analysis to compute the amplitude of modes created in the waveguide by external excitations Simulate the dispersive propagation of waveforms along the waveguide.)

最小二乘支持向量机，用于进行函数的回归分析(Least squares-Support Vector Machine,Used for regression analysis of functions)

applying cropping, median filter, contrast stretching and laplacian filter

鱼群算法的matlab工具箱，可在matlab中设定路径进行使用(yuqunsuanfa tool for matlab, fish swarm algorithm matlab toolbox)
