用matlab编写的谱方法基本程序,相信对大家有用。(Some basic matlab programs on spetral methods)

compression and decompression for image

Included are the files wav1.m, wav2.m, wavecoef.mat and readme. wav2 function implements the tree structured wavelet transform of the input matrix, up to the given level of decomposition. Wav2 uses another function called wav1, which takes the well known wavelet transform of the given matrix. Daubechies wavelet coefficients are used for wavelet transform operation wahich is saved in wavcoeff.mat. (Included are the files wav1.m, wav2.m. wavecoef.mat and readme. wav2 function biennium max the tree structured wavelet transform of t he input matrix. given up to the level of decomposition. Wav2 use s wav1 another function called, which takes the well known wavelet transform of the given matrix. Daubechies wavelet coeffici separations are used for wavelet transform operation w ahich is saved in wavcoeff.mat.)

说明：  doa估计的三种方法，包含MUSIC算法，ESPRIT算法，压缩感知的算法。(Three methods of doa estimation)

求解接触刚度，用经典的Hertz方法求解理想情况下 刚度随载荷变化的关系(contact stiffness)

说明：  多项式拟合用于处理实验数据的一种有效方法，简单实用。并且举了一个例子三次拟合(Polynomial fitting of experimental data for processing is an effective method of simple and practical. And cited an example of three fitting)

CUBIC spline analysis

matlab揭秘的附件， 带图带源码文件，1、3章(the matlab Secret Annex, the band diagram with source files, 1,3 Chapter)

binary phase shift key

利用神经网络优化BP神经网络，能有效提高BP神经网络对非线性的拟合精度，效果较好。(Using neural network optimization BP neural network, BP neural network can effectively improve the accuracy of nonlinear fitting better.)
