用MATLAB在M文件里编写连续谱密度函数(matlab)

fit_ML_normal - Maximum Likelihood fit of the normal distribution of i.i.d. samples!. Given the samples of a normal distribution, the PDF parameter is found fits data to the probability of the form: p(r) = sqrt(1/2/pi/sig^2)*exp(-((r-u)^2)/(2*sig^2)) with parameters: u,sig^2 format: result = fit_ML_normal( x,hAx ) input: x - vector, samples with normal distribution to be parameterized hAx - handle of an axis, on which the fitted distribution is plotted if h is given empty, a figure is created. output: result - structure with the fields sig^2,u - fitted parameters CRB_sig2,CRB_u - Cram?r-Rao Bound for the estimator value RMS - RMS error of the estimation type - ML

采用改变mapping circuit的方法,变QPSK为MSK仿真.(circuit used to change the mapping method to change QPSK MSK simulation.)

利用matlab进行主成分分析，有现成的代码和数据，主成分分析例子(Use of matlab for principal component analysis, have a ready-made code and data, principal component analysis example )

基于chebyshev的水声信号分析，最小均方误差（MMSE）的算法，多目标跟踪的粒子滤波器。( Based chebyshev underwater acoustic signal analysis, Minimum mean square error (MMSE) algorithm, Multi-target tracking particle filter.)

说明：  K-MEANS算法是输入聚类个数k，以及包含 n个数据对象的数据库，输出满足方差最小标准的k个聚类。 (K-MEANS algorithm is the input number of clusters k, and n a data object that contains the database and output to meet the standard minimum variance k-clustering.)

数字图像处理的（MATLAB）实现，要安装超星阅读器(Digital Image Processing (MATLAB) to achieve, to install Superstar Reader)

It will perform bit plane slicing operation on input image.

here we will estimate delay time added to the channel and we will plot the error

em算法的代码，以及K-means算法代码(em algorithm code, and the K-means algorithm code)
