a Matlab code to simulate the semiconductor laser

A new non-linear least squares (NLS) DRSS location estimator that uses correlated shadowing information to improve performance is introduced. The existing maximum likelihood (ML) estimator and Cram′er Rao lower bound (CRLB) for RSS-based localization given do not account for correlated shadowing.

四旋翼无人机SIMULINK建模，PSO_SA优化PID参数 reverse.m 作用：将History表中的string形式的key值转换为赋给九个全局变量temp00， ... ,temp08运行sum1.slx，可以直接观察此组参数的波形。 History 作用：映射表，将一组参数（temp00, ..., temp08）映射到这组参数的ITAE指标。 trojectory.m 作用：定义一条路径并进行路径压缩，通过不断向sum.slx传递位置参数，控制无人机运动，并接受无人机运动过程，做出无人机运动位置图像。 sum1.slx 作用：从外部接受一组位置关系（x,y,z）,模拟无人机由原点(0,0,0)运动到该位置并保持稳态这个过程中无人机的位置变化，并向外部反馈。 PSO_3D.m 作用：调用sum3D.slx，通过PSO得到内循环最优解的参数。 sum3D.slx 作用：获取.m文件中设置好的全局变量的值，模拟内循环三个角度的变化。 PSO_History.m 作用：调用sum9D.slx，通过PSO得到外循环最优解的参数，此过程已被History表优化。 PSO_SA.m 作用：调用sum9D.slx，通过PSO得到外循环最优解的参数，此文件在PSO_History.m基础上被模拟退火算法优化(Four rotor UAV SIMULINK modeling, PSO_SA optimize PID parameters)

详细的介绍了matlab的实践原理，适合初学者(Detailed introduction to the principles of the practice of matlab for beginners)

如果你有一个三维校准对象，你可以应付一个单一的形象。为了获得令人满意的校正结果，对象应包括整个图像以及可能的。此外，多张图片的支持。那么， 图像应捕获不同的观点改变了相机 方向和距离。如果在一个平面标定目标单一 形象是不够的和一套图像是需要解决所有 摄像机的参数。的坐标平面控制点应 被选中，这样的Z坐标成为为零。三维坐标股 毫米和图像坐标单位是像素。校准坐标 系统是用右手。原产地的图像坐标系中 左上角， X轴是正确的和Y轴向下。(If you have a three-dimensional calibration object, you can cope with a single image. Calibration In order to obtain satisfactory results, the target should include the entire image, as well as possible. In addition, the support of many pictures. Then, the image should capture different points of view camera has changed the direction and distance. If a planar calibration target at a single image is not enough and a set of images are necessary to solve all the camera parameters. The coordinates of horizontal control points should be selected, such as Z coordinates become zero. Unit-mm three-dimensional coordinates and image coordinates are pixel units. Calibration are right-handed coordinate system. Origin of the image coordinate system in the upper left corner, X-axis and Y are correct under axial.)
