仿真图是速度、距离、幅度三维图像，代码里有很完整的注释和解释，有CDF三角函数曲线/三维曲线图，PLS部分最小二乘工具箱,重要参数的提取，这个有中文注释，看得明白，部分实现了追踪测速迭代松弛算法，实现了对10个数字音的识别。- FIG simulation speed, distance, amplitude three-dimensional image, Code, there are very complete notes and explanations There CDF trigonometric curve/3D graphs, PLS PLS toolbox, Extract important parameters, The Chinese have a comment, understand it, Partially achieved tracking speed iterative relaxation algorithm, To achieve the recognition of 10 digital sound.
