轻松实现GM模型的操作 GM(1-N)

对图像进行非下采样小波变换，得到一个低频子带和若干个高频子带。(Under the image of non-sampling wavelet transform, to get a low-frequency sub-band and a number of high-frequency sub-band.)

说明：  这是一个有关frft的matlab的程序，请好好利用吧(a programm about frft,please take full use of it)

卡尔曼滤波器在目标跟踪中应用仿真研究，采用VD算法(application simulating of kalman filer in tracking targets )

说明：  神经网络激活函数代码，有代码有图，可以直接用来学习使用。(Neural network activation function code, there are codes and graphs, can be directly used to learn to use.)

Matlab图形图像处理例程。应用MATLAB图形函数和绘图实例(Matlab graphics and image processing routines. Application of MATLAB graphics functions and drawing examples)

关于连续小波变换的matlab程序，使用molet小波的连续小波变换(On continuous wavelet transform matlab procedures, the use of continuous wavelet transform wavelet morlet)

Low-pass filter design

Hi..this BCJR algorithm detail

PLS 的Matlab代码,用于线性降维和回归分析(matlab source code for partial least squares)

说明：   基于matlab 的叠加高斯白噪声的正弦信号频谱分析，给定正弦函数x=sin(2πf0n/N+π/3)+sin(2πf1n/N+π/4)，设定f0.f1的值，加了噪声之后做快速傅里叶变换，在matlab中分析其频谱，验证是否与f0,f1的值符合。再变换N值，看随着N值的变化对应点是否符合及有何变化。(Matlab based on the superposition of Gaussian white noise sinusoidal signal spectrum analysis, given the sine function x = sin (2蟺f0n/N+蟺/3)+sin (2蟺f1n/N+蟺/4) set value of f0.f1, do a quick noise Fourier transform to analyze the spectrum in matlab, verify that with f0, in line with the value of F1. Transform the value of N, see change as the value of N corresponding points of compliance and what changes.)
