简单的读谱器，输入相应的音乐简谱，就可以实现音乐的播放(Simple to read music, input the corresponding music notation, music playback can be achieved)

说明：  在spectral method for matlab、Spectrral and High-order methods in Engineering、Matlab computing science的书中附带程序(computational spectral method books code)

non linear B spline curve fitting

岭回归函数，基于SVD分解的岭回归函数，已经证明了是非的有用和强大( center input and output, so we can estimate w0 separately since we don t want to shrink w0 )

均匀圆阵的常规波束形成，没有使用自适应波束形成。uniform circle array beamform(uniform circle array beamform)

此文件包含了zoom-fft算法语言，结果与FFT对比图片输出(This file contains ZOOM-FFT algorithm language, the results are compared with FFT image output.)

本算法是个B样条曲线拟合算法，包括2D的和3D的两种曲线拟合算法。用户可以自己设定拟合的点数，也可以让算法根据拟合效果自动确定。(This algorithm is a B-spline curve fitting algorithms, including 2D and 3D two curve fitting algorithm. Users can set their own fitting points, but also allows the algorithm automatically determined according to the fitting effect.)
