二阶Butterworth滤波器, 可以直接用于数字信号处理，里面有输入输出说明，很详细(Second Order Butterworth Band-Pass Filter)

说明：  关于OFDM的经典文献，包括simulinc仿真的各个环节。(The classic literature about OFDM, including every link of simulinc simulation. )

各种矩阵相称的算法时间比较，有MATLAB自带矩阵，分制法，循环计算，Strassen算法(Commensurate with the various matrix algorithm time, there MATLAB own matrix, a scoring system, cyclic calculation, Strassen algorithm)

MEMS陀螺的allan方差程序，运行已通过(Allan variance procedure of the MEMS gyroscope, the run has passed)

这个是使用spss分析的一个关于快递业务满意度的一个调查分析(This is the use of SPSS analysis on an express service satisfaction an investigation analysis)

target tracking The CV and CA models can be used to model the distance between front and host vehicles, but we don’t know when a specific model should be used. The interacting multiple model (IMM) estimator [1] is an algorithm which can be used to handle such case. In IMM algorithm, at time k the previous estimates from the multiple models are mixed based on the mixing probabilities to generate different mixed initial conditions for different filters.

根据公式I（n-1）=（1-In）/n 令I11=0计算I1 到I10； 根据公式In=1-nI(n-1) 令I0=0.6321 计算I1到I7； 根据公式X2=a ， 令a=2，计算X的值。(According to the formula I(n-1)=(1-In)/n ，set I11 equals zero，and count I1 to I10. According to the formula In=1-nI(n-1)，set I11 equals zero，and count I1 to I10. According to the formula X square equals a ，set a equals two ，then calculate X )

音频处理要用到的几个函数，包括A率压缩，u率的，以及其附属的傅里叶变换、滤波等等，总之包含了一个音频信号简单处理的大部分程序(Audio processing functions )

可以看到 变步长未必会需要更长的时间 因为它是一种自适应的方式 如果某阶段情况理想的话 就会用最大步长来做 那就会很快 (can see variable step may not need a longer period of time because it is an adaptive way if a certain phase of the the ideal would be the greatest step will be to do it quickly)
