生成《matlab扩展编程》中对于HMM训练的sammples.mat程序，自己编写，已通过测试。 (Generation " matlab programming expansion" in the HMM training sammples.mat procedures, I have written a complete source code, has been tested. )

使用MATLAB实现的BP神经网络的回归功能，代码非常的简洁(using MATLAB BP neural network regression function, the code is very simple)

编写针对一个搜索点宏块比较的下面两个匹配函数：均方误差(MSE)、绝对值误差(MAD)。函数名直接使用简写。要求当前帧和参考帧的数据均采用二维数组表示。(Writing for a search point macroblock compare the following two matching functions: the mean square error (MSE), absolute error (MAD). The function name directly using shorthand. Requirements of the current frame and reference frame data are used two-dimensional array.)

说明：  先用.txt文件导出杆系结构和梁系结构的用于节点校核的数据，然后用matlab程序计算即可进行构件验算(time. Txt file is derived bar structure and the structure of the beam system for checking the data node, then Matlab can be calculated for checking Component)

Maximally stable extremal regions (MEX MATLAB to C++) implementation

灰色理论认为系统的行为现象尽管是朦胧的，数据是复杂的，但它毕竟是有序的，是有整体功能的。灰数的生成，就是从杂乱中寻找出规律。同时，灰色理论建立的是生成数据模型，不是原始数据模型，因此，灰色预测的数据是通过生成数据的gm(1,1)模型所得到的预测值的逆处理结果。(Gray theory that the behavior of the system even though the phenomenon is dim, the data is complex, but still it is ordered, there is a whole function. Gray number generation, that is, from the clutter to find out the laws. Meanwhile, the gray theory is to generate the data model, not the original data model, so gray prediction data by generating data gm (1,1) model predicted values ​ ​ obtained result of the inverse process.)
