OCT信号模拟 很理想化 但对初学者帮助较大(OCT signal simulation is ideal for beginners but for more help)

说明：  hdu 2529,第2529题的结题报告 (answer for acm on hdu acm)

the code i have uploaded estimate the position of speaker,in environment put a number of microphones that by extended kalman filter estimate the position of speaker

说明：  利用Matlab编写程序实现以下功能：以多项式形式输入系统前向通路传递函数和反馈回路传递函数，计算系统开环增益，判定型别，根据控制系统劳斯稳定判据原理，列出得到的任意阶次系统的劳斯表，判定闭环系统稳定性，若不稳定给出具有正实部极点的数目。 （1）根据用户输入的稳定度a，计算稳定的开环增益K的范围； （2）确定系统的最大稳定度a,计算相应的开环增益K的值。 (The use of Matlab programming to achieve the following functions: polynomial in the form of input system transfer function to the path and feedback loop transfer function, system open-loop gain calculation to determine type, according to Routh stability criterion control system theory, has been listed in the system of arbitrary order Routh table to determine the stability of the closed-loop system, if the stability of a positive real part gives the number of poles. (1) According to the stability of the user to enter a, calculation of the stability of the open-loop gain of the scope of K (2) to determine the most stable system a, the calculation of the open-loop gain of the corresponding K value.)

The floatAxisX m-file enables you to plot parameters with different units (eg. temperature, salinity and density versus depth) on the same axes having the x-axis for the parameters "floating" below. FloatAxisY plots floating axes on the left-hand side of the plot. The number of parameters plotted is not limited. Type ctdplotx or ctdploty at the Matlab command prompt for a demo.

Add Gaussian white noise (mean=0 and variance=0.05 ) to the image using imnoise command. Now use fftshift command to put all zero frequencies in the middle. Low-pass filter this function by applying a mask saving only the central Fourier coefficients. Set the mask width to 255 and create the filtered image.
