压缩感知中一种测量方法。介绍如何构造测量矩阵。(Compression in a perceptual measurement method. Introduce how to construct measurement matrix.)

This is a code of Pseudo-Arc Length Continuation Method , the method can be used for solving the nonlinear equations, the principle can re found in some text books. In the code,I prove the agreement of the code with other methods

动态方式观察物体坠落的过程，从而达到动态的仿真效果。(The dynamic way observation object crashes process, thus achieves the dynamic simulation effect. )

这是一个粒子群优化算法在求函数极值方面的应用，以球函数为例，说明了PSO算法的可行性(Feasibility This is a particle swarm optimization algorithm to find function extreme aspects of the ball function to illustrate the PSO algorithm)

Least squares sinusoid fit algorithm described in IEEE Standard for Digitizing Waveform Recorders (IEEE Std 1057): Algorithm for three-parameter and four-parameter least squares fit to sinewave data using matrix operations. The algorithm is (in most cases) really quick. If the signal frequency is a guess, it has to be close to true frequency value. For further information, consult IEEE Std 1057 and/or IEEE Std 1241 documentation. Now also fits complex sinusoids i.e. phasors with noise and o

it is matlab code that smoothing the signals level so that we can know it

通信中应用的16QAM的仿真 在AWGN信道下的仿真 误码率等(Communication 16QAM application of simulation in the AWGN channel bit error rate simulation)
