OPTIMISATION OF SIGNAL BY PARTICULE SWARM METHOD

These are MATLAB codes for implementing Elliptical Bandstop and Bandpass filters for use in Digital Signal Processing

osgearth 矢量数据处理包含国际线和省级线(Osgearth vector data processing includes international line and provincial line)

说明：  快速迭代收缩阈值算法，FISTA用一种更为聪明的办法选择序列{xk}，使得其基于梯度下降思想的迭代过程更加快速地趋近问题函数F(x)的最小值。FISTA的缺点是：Lipschitz常数L(f)不一定可知或者可计算。(Fast iterative contraction threshold algorithm, FISTA uses a more clever method to select the sequence{xk}, making its iterative process based on the gradient descent idea more quickly approach the minimum value of the problem function F(X). The disadvantage of FISTA is that the Lipschitz constant L(f) is not necessarily known or computable.)

Simulation of digital baseband modulation,it is very good for the users to deepen their understanding

说明：  一个小波消噪的matlab例子，里面有源程序 希望可以帮到大家(a denoise example of wavelet,)

说明：  水平层状介质，地震合成记录matlab程序(The level of layered media, seismic synthetic seismogram program matlab)

频谱估计Automatic Spectral Analysis-Matlab code(Accurate estimates of the autocorrelation or power spectrum can be obtained with a parametric model (AR, MA or ARMA). With automatic inference, not only the model parameters but also the model structure are determined from the data. It is assumed that the ARMASA toolbox is present.)
