this pdf details about hoe to write mat lab code efficiently with in less time

对高斯输出的hmm的源程序，对hmm的学习者有很大帮助

说明：  电力系统节点导纳矩阵的形成，自己编写的供大家参考，谢谢(Power system nodal admittance matrix of the form, I have written for your reference, thank you)

系统辨识中的随机牛顿法，用于系统参数辨识(System Identification random Newton method for system parameter identification)

在一定的约束条件下，其输出与一给定函数（通常称为期望输出）的差的平方达到最小，通过数学运算最终可变为一个托布利兹方程的求解问题。维纳滤波器又被称为最小二乘滤波器或最小平方滤波器，目前是基本的滤波方法之一。维纳滤波是利用平稳随机过程的相关特性和频谱特性对混有噪声的信号进行滤波的方法，1942年美国科学家N.维纳为解决对空射击的控制问题所建立，是40年代在线性滤波理论方面所取得的最重要的成果。(Under some constraint conditions, the output with a given function (often referred to as expected output) the square of the difference between the minimum, through mathematical operation can be turned into a final taub Leeds equation to solve the problem.Wiener filter is also known as least squares filter or least square filter, is now one of the basic filter method.Wiener filtering is to use the related characteristics of stationary random process and spectrum characteristics of mixed with noise signal filtering method, scientists in the United States in 1942 n. wiener established to solve the control problem of empty shooting, is 40 s in the theory of linear filtering is the most important results.)

针对离散系统的阶跃信号、正弦信号和方波信号，设计离散PID(Step for the discrete-time systems signal, sinusoidal signal and the square wave signal, the design of discrete PID)

hi, this is good progrramm.

reads stl files in matlab

this is audio retrieval based on the feature extraction such as FFT, STFT, and Power Spectral Density

《数字信号处理及其MATLAB实现》教材配套的程序集，很全很强大。(" Digital signal processing and MATLAB to achieve" material supporting assembly, it is all very strong.)
