This function quickly finds local peaks or valleys (local extrema) in a noisy vector using a user defined magnitude threshold to determine if each peak is significantly larger (or smaller) than the data around it. The problem with the strictly derivative based peak finding algorithms is that if the signal is noisy many spurious peaks are found.

OOMP算法是压缩传感的一种算法，其对OMP算法进行改进，提高了正确率。(OOMP Compressed sensing algorithm is an algorithm to improve its OMP algorithm to improve the accuracy.)
