MATLAB时频分析的原代码（一部分）！！(Time-frequency analysis of the original MATLAB code (part of)! !)

说明：  cost207信道文件 matlab仿真程序 可以跑 应该是网上关于此的最常见的(cost207 Channel document Matlab simulation program can be run on the Internet is the most common)

基于MATLAB平台上，计算HU矩的算法编程。可以不用花时间去考虑怎么计算那些不变矩了。(MATLAB-based platform, the algorithm for calculating the moment HU programming. Can not take the time to consider how those calculated by moment invariants.)

小波模极大值边缘检测+膨胀+闭操作+边缘跟踪 得到清晰边缘(The modulus maxima of wavelet transform edge detection+ expansion+ close operation+ edge tracking Get the clear edge)

一个无刷电机仿真的模型，matlab环境，可以计算电机性能（注意：仿真的时候，对计算机硬件要求可能有点高）(a model of brushless DC motor (BLDC motor))

代码主要计算Daubechies紧支集滤波器系数L0_d和H1_d,然后采用这两个系数对信号进行小波分解(The main calculation code compactly supported Daubechies filter coefficients L0_d and H1_d, then the use of these two coefficients of wavelet decomposition signals)

Matlab中没有现成的Hermite插值函数，必须编写一个M文件实现插值。 设n个节点的数据以数组x0 （已知点的横坐标）， y0（函数值）， y1（导数值）输入（注意Matlat的数组下标从1开始）， m个插值点以数组x 输入，输出数组y 为m 个插值。编写一个名为hermite.m的M文件。 (Matlab is not off-the-shelf Hermite interpolation function, we must realize the preparation of a document M interpolation. N nodes for the data to an array x0 (known point of abscissa), y0 (function value), y1 (numerical derivative) input (note the subscript Matlat array starting at 1), m to the array of interpolation points x input and output array y for m months interpolation. Hermite.m the preparation of a M-file.)
