image-processing-data-hiding-code

说明：  这是一个信赖域方法的程序，简单实用，对初学者非常有用。(This is a trust region method procedures, simple, practical, very useful for beginners. )

分集最大比合并系统,对应有SISO，SIMO，简单明了，具有很大的价值。(diversity，MRC，including siso and simo,it is simple but useful.)

计算图想的傅里叶变换并显示其频谱，本设计中显示了四种图像的频谱，供大家学习和参考，比较每一种频谱的不同！(Map to calculate and display the Fourier transform of the spectrum, the design spectrum shows four images for all to study and reference, compare the different spectrum of each!)

说明：  这个程序主要的功能是实现了基于特征空间法的静态最小二乘恒模算法的方向图(This program is the main function realization based on feature space method static least-squares constant modulus algorithm direction map)

应用lqr方法实现四旋翼姿态角控制，内附matlab代码(Matlab implementation of helicopter LQR control)

请大家帮忙看看问题出在哪里,a0、a1、a2还可以，A3以后就不对了(Matlab computing applications lamb wave dispersion curves, group velocity and phase velocity calculation.)

说明：  对数据进行因子分析，得到的是降维的结果。可用来做基本的降维，故障诊断，图像分解(Through factor analysis of the data, we get the result of dimension reduction)

This is a simple example in Matlab where a array is introduced
