This ZIP file includes the algorithm for hiding the text file in image with LSB.

自己编写的MATLAB函数，实现对图像的旋转。B是原图像，灰度或彩色，alpha是旋转角度（角度或弧度单位均可），A是旋转后图像。旋转后图像信息尽可能不损失。(I have written MATLAB function, to achieve image rotation. B is the original image, grayscale or color, alpha is the angle of rotation (degrees or radians per unit), A is rotated images. Rotation after the image information as possible without loss.)

哥伦比亚大学编写的MATLAB-HTK工具箱(Columbia University toolbox written in MATLAB-HTK)

图像去噪TV模型及Matlab实现， ROF是相对比较老但是比较经典的算法之一，这里对其进行了小的变动。(TV denoising model and Matlab realized, ROF is one of the relatively old but more classical algorithm, where its small change.)

these matlab simulation will be useful to those who search for voltage source control of synchronous motor using mosfet

Bit Error rate Simulation

新的2维角度估计的高分辨方法。该方法首先建立基于范数约束的最优化问题的目标函数；然后用迭代算法沿均匀面阵接收数据的方位向求最小化目标函数的稀疏解，得到方位、俯仰角耦合的空间角频率，并分离信号；最后对每个分离的信号，沿面阵俯仰向求稀疏解，得到信号的俯仰角，进而求得对应的方位角。(The new high-resolution 2-D angle estimation method. Firstly, the establishment of an objective function optimization problems based on norm constraint then iterative algorithm along with uniform orientation plane array receives data to seek to minimize the objective function is sparse solution, get directions, spatial frequency coupling angle pitch angle, and separated signals Finally for each signal separation along the sparse area array pitch to seek solutions to obtain the pitch angle of the signal, and then obtain the corresponding azimuth.)
