fit_ML_normal - Maximum Likelihood fit of the laplace distribution of i.i.d. samples!. Given the samples of a laplace distribution, the PDF parameter is found fits data to the probability of the form: p(x) = 1/(2*b)*exp(-abs(x-u)/b) with parameters: u,b format: result = fit_ML_laplace( x,hAx ) input: x - vector, samples with laplace 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 u,b - fitted parameters CRB_b - Cram?r-Rao Bound for the estimator value RMS - RMS error of the estimation type - ML

MATLAB文件。《超宽带无线电基础》配套程序，第二章第3个例程。用于产生QPSK编码。(MATLAB file. Ultra-wideband radio base matching program, the first chapter of a routine. QPSK for generating code.)

资源分配网络的主要思想是当神经网络在学习过程中发现“未建模”的样本时，就分配新的计算节点。(The main idea of ​ ​ the network resource allocation is when the neural networks found in the learning process " is not modeling" of the samples, to assign a new compute nodes.)

将声音文件在时间轴上分割成几段，分别将段的秩序及某些段内的秩序颠倒，从而实现了对声音文件的加密。首先，先读取一个声音信号，对信号做1024点FFT变换，取完点之后，分成四个向量，四个向量组成一个矩阵，再对每一个向量进行转置，再重新整合，从而就实现了回密的过程。(Sound files on the timeline will be divided into paragraphs, each paragraph of the order and reversed the order of some paragraphs to realize the encryption of sound files. First, the first reading of a voice signal, the signal was 1024 points FFT transform, check after the completion point, divided into four vectors, the four vectors form a matrix, then for each vector transpose, re-integration, which will achieve a return to close the process.)

压缩感知目前广泛应用于雷达成像或得超分辨稀疏成像，该文件为压缩感知三维成像。(Compressed sensing has been widely applied in radar imaging or sparse super resolution imaging, the file is compressed perception three-dimensional imaging. )
