OS-CFAR
有序统计量恒虚警检测——OS-CFAR检测器：包括对于无目标、仅有噪声的信号进行OS-CFAR检测的仿真，以及对于含目标、且在瑞利杂波背景下的OS算法仿真。一些程序主要是为了绘图，画出OS-CFAR检测过程中的信号波形以及检测门限对比图；而另一些程序是为了计算OS-CFAR检测过程中的检测概率和虚警概率。(OS-CFAR detectors: simulations of detection to signals with no target but noise only, as well as signals with target and the background of Rayleigh clutter. Some programs are aimed at giving pictures of the signals and detectiong threshold in the process of detection using OS-CFAR algorithm, while other programs are aimed at calculating the detecting rate and false alarm rate of OS-CFAR algorithm.)

eigenvaluefield33
Calculate the eigenvalues of many 3x3 real symmetric matrices.(Calculate the eigenvalues of many 3x3 real symmetric matrices. Computation is non-iterative, based on fully vectorized matlab matrix operations, and GPU computation is supported. It is fast and efficient for processing a number of 3-by-3 matrices at once. This code particularly suits tensor/Riemannian calculus in 3D, visualization/analysis of volumetric tensor images, image Jacobian/Hessian analysis, stress/tensile strength computation on tensor fields, three dimensional diffusion processes, determining the rotation axes of a motion field, etc....)
