matlab DCT zigzag function

matlab 学习技巧，现在把我用的，也就是对我帮助很大的留个文件传上去，希望对大家有用，第一入门与提高(matlab learning skills, and now I use, which is a great help to me to leave a document passed up, we want to be useful, the first entry and improve)

信号信噪比计算，验证对比了matlab中的多种信噪比计算方法(compare the calculation of SNR )

This Embedded MATLAB Function implements an extended Kalman filter used to estimate the states, road surface and mass of a quarter car model.

本程序是对V-BLAST系统及其检测算法的仿真，可采用BPSK,QPSK,16QAM,64QAM调制。检测算法为ML，MMSE,ZF,以及采用迫零的连续干扰消除检测算法。(This procedure is the V-BLAST system and its detection algorithm simulation, can be used BPSK, QPSK, 16QAM, 64QAM modulation. Detection algorithm for the ML, MMSE, ZF, and the use of zero-forcing successive interference cancellation detection algorithm.)

function [ H ,S ] = HS( f ) UNTITLED2 Summary of this function goes here Detailed explanation goes here syms x1 x2 f1=diff(f,x1) f2=diff(f,x2) S= [f1 f2] H = [diff(f1,x1) diff(f1,x2) diff(f2,x1) diff(f2,x2)] end s0=subs(S,findsym(S),[0 0])(function [H, S] = HS (f) UNTITLED2 Summary of this function goes here Detailed explanation goes here syms x1 x2 f1 = diff (f, x1) f2 = diff (f, x2) S = [f1 f2] H = [diff (f1, x1) diff (f1, x2) diff (f2, x1) diff (f2, x2)] end s0 = subs (S, findsym (S), [0 0 ]))

说明：  本程序用来求转子的临界转速，模型为有限元模型(This procedure is used to seek the rotor critical speed, the model for the finite element model)

在瑞利衰落和高斯白噪声下qam调制对于不同信噪比的误码率(bit error rate of the Qam modulation in Rayleigh fading and Gaussian white noise for different signal to noise ratio)

多视图几何三维重建程序，经典算法matlab，非常全，对三维重建很有帮助。(Multi-view geometry of three-dimensional reconstruction procedure, the classical algorithm matlab, very wide, very helpful for three-dimensional reconstruction.)

convolutional code is a kind of code memory, in any given unit of time, the encoder output n this time not only with the elements of the k input, but also with the input m. Convolutional codes are usually stated as : (n, k, m)
