基于matlab的抗积分饱和PID控制源程序(Anti-windup PID control)

光学弗朗和费衍射模拟的Matlab源代码(Fraunhofer diffraction optical analog of the Matlab source code)

The error is detected efficiently during the motion estimation process

心音信号的DCT域变换压缩编码，LLoyld最佳量化与霍夫曼编码，利用心电R波进行分帧，在不到1 左右失真度的情况下达到了6.0以上的压缩比(Heart sound signals on DCT transform coding, LLoyld optimal quantization and Huffman coding, the use of ECG R wave sub-frame, less than about 1 in the case of distortion to achieve a compression ratio of more than 6.0)

采用了小波去噪的思想，关于超声波倒车雷达测距的，外文资料里面的源代码。( Using wavelet denoising thought, About ultrasonic parking radar ranging, Foreign materials inside the source code.)

原始单纯形法（大M法，无需给出初始基变量）。输入：C是n维行向量，A是m*n的系数矩阵，b是m维列向量 输出：x最优解（如果有的话），fval最优值，flag解的状态说明，interation求解时的循环次数(The original simplex method (big M method, without giving the initial basic variable). Input: C is the n-dimensional row vector, A is the coefficient matrix of m* n, b is the m-dimensional column vector Output: x the optimal solution (if any), fval optimal value, flag state solution description, interation when the number of cycles to solve)

用MATLAB实现的RSA。界面友好，可加密任意长度字符串。(MATLAB RSA. Friendly interface, encryption arbitrary length of the string.)
