HidingTextFilesInImageWithSteganography

用来计算十字交叉点的中心位置,可以达到亚像素精度，在三维重建中经常会在物体表面做标志，本算法用于计算十字标记中心(to calculate the center of a cross image)

matlab 下高斯和瑞丽分布下QPSK信号的产生，发送和接收以及误码率分析(matlab under the Gaussian distribution, and Ruili QPSK signal generation, transmission and reception, and bit error rate analysis)

Crypto graphy matlab coding

LDPC码的Matlab仿真，希望对大家有用， (LDPC code of the Matlab simulation, in the hope that useful to everybody,)

The COFDM simulation

Matlab简单模拟双缝衍射的平面光强分布及一维光强分布(Matlab simulation of the intensity distribution simple double-slit diffraction plane and the one-dimensional intensity distribution)

说明：  基于KPCA的对葡萄酒数据的降维处理，将13维数据降维成小于13维的，可选(KPCA-based dimensionality reduction of wine data)

说明：  这是一本关于MATLAB编程的电子图书,方便大家使用.(This is a book about MATLAB programming e-books, to facilitate the use of everyone.)

region growing: Perform segmentation by region grow1ng. [G, NR, SI, TI] = REGIONGROW(F, SR, T). Scan be an array (the same size as F) with a 1 at the coord1nates of every seed point and 0s elsewhere. S can also be a single seed value. Similarly, T can be an array (the same size as F) containing a threshold value for each pixel in F. T can also be a scalar, in wh1ch case it becomes a global threshold.

说明：  MATLAB SIMULINK仿真程序，主要实现光伏电池及其最大功率点跟踪。(Matlab Simulink simulation program, mainly to achieve photovoltaic cells and their maximum power point tracking.)
