是机器学习的例程，包括最小二乘法、SVM、神经网络、1_k近邻法,是信号处理的基础，使用起来非常方便，从先验概率中采样，计算权重，GPS和INS组合导航程序，代码里有很完整的注释和解释。- Machine learning routines, Including the least squares method, the SVM, neural networks, 1 _k neighbor method, Is the basis of the signal processing, Very convenient to use, Sampling　a priori probability, calculate the weight, GPS and INS navigation program, Code, there are very complete notes and explanation.
