说明：  matlab函数的一个例子！！就是描述扩展卡尔曼滤波的一个MATLAB算法。(this is an example about ekf!extended kalman filter algorithms applied matlab)

PSO algorithmcode1.rar(PSO algorithmcode1.rar it is good)

implementation of image cosegmentation using color reward strategy and active contours. I run this code and it was correct. this code is free bye its author Fanman Meng.

Markov Chain model for regime switching time series

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.)

说明：  针对光照不均匀条件下光伏阵列 P-V 输出特征呈现多波峰，传统算法无法摆脱局部最优值的缺点，该文提出了一种基于细菌觅食的优化算法，并首次应用于光伏阵列的最大功率点跟踪（MPPT）。(In order to solve the problem that the photovoltaic array P-V output characteristic presents multi peaks under the condition of uneven illumination, the traditional algorithm can not get rid of the local optimal value Based on the optimization algorithm of bacterial foraging, it is applied to the maximum power point tracking (MPPT) of photovoltaic array for the first time. The algorithm introduces the trend operation, which is used for the local optimization)
