有详细的注释，借鉴了主成分分析算法（PCA），处理信号的时频分析，研究生时的现代信号处理的作业，包含CV、CA、Single、当前、恒转弯速率、转弯模型，模拟数据分析处理的过程，包含特征值与特征向量的提取、训练样本以及最后的识别。- There are detailed notes, It draws on principal component analysis algorithm (PCA), When processing a signal frequency analysis, Modern signal processing jobs when the graduate, It contains CV, CA, Single, current, constant turn rate, turning model, Analog data analysis processing, Contains the eigenvalue and eigenvector extraction, the training sample, and the final recognition.
