基于多观测矢量的正交匹配追踪算法 正确估计信号的DOA(MMV bases on omp used to DOA)

寻找测试样本的最近邻，可以有效的用于用于模式识别，信号处理(This is a small but efficient tool to perform K-nearest neighbor search, which has wide Science and Engineering applications, such as pattern recognition, data mining and signal processing. The code was initially implemented through vectorization. After discussions with John D Errico, I realized that my algorithm will suffer numerical accurancy problem for data with large values. Then, after trying several approaches, I found simple loops with JIT acceleration is the most efficient solution. Now, the performance of the code is comparable with kd-tree even the latter is coded in a mex file. The code is very simple, hence is also suitable for beginner to learn knn search.)

An electric wheelchair uses a motor with a torque constant of 1.1 Nm/A, powered from a 24 V battery, with an internal resistance of 0.25Ω. We are interested in designing a controller with 44 Nm continuous torque capability, both in driving and braking modes at all speeds, with the widest possible operating speed range, both forward and reverse direction using the given battery.
