基于马尔科夫链概念，5*5矩阵的概率转移矩的matlab实现(Based on the concept of Markov chain, the realization of the 5* 5 matrix s transfer probability matrix in matlab)

说明：  边缘检测灰度调整与柱状图的MATLAB程序。希望对大家有帮助。(Gray-scale edge detection and histogram to adjust the MATLAB program. We want to help.)

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.)

非线性自抗扰控制器，仿真通过，可以用来学习和改进(The nonlinear ADRC controller can be used to learn and improve by simulation.)

免疫算法的matlab代码，应该比较好用，谢谢支持！(immune algorithm Matlab code, it should be more convenient, thank you support!)

以5*5为模板在一幅灰度图像中寻找像素值大于给定阈值的所有点(To 5* 5 as a template to look at a gray image pixel value is greater than a given threshold for all points)

Eigenfaces is used to representing a face by projecting original images onto a face space defined by eigenvectors, and then a new face is compared to known faces by calculating the distance between their projections onto face space. (Eigenfaces is used to representing a face b y original projecting images onto a face space d efined by eigenvectors. and then a new face is compared to known faces by c alculating the distance between their project ions onto face space.)

this programme define a circuit-based simulation model for a PV cell in order to allow estimate the electrical behavior of the cell with respect changes on environmental parameter of temperature and irradiance

说明：  修正BBO晶体折射率色散公式中错误的系数 ，完成βBBO晶体Ⅱ类匹配的SPDC（共线情况）并计算相位匹配角。此时的相位匹配角为能 产生纠缠光子对的最小切割角。另附一份参考文献，详细的说明此类实验的步骤与细节。(Correct the wrong coefficient in the refractive index dispersion formula of BBO crystal, complete the type II matching SPDC of BBO crystal and calculate the phase matching angle. The phase matching angle is the minimum cutting angle that can produce entangled photon pairs. In addition, a reference is attached to explain the steps and details of such experiments in detail.)
