说明：  所给的m文件中有详细的构造三对角分块矩阵的方法，而且构造的分块矩阵采用的是稀疏存储的方法，适用于大型三对角分块矩阵的构造(There are detailed methods to construct tridiagonal block matrix in the given m file, and the method of sparse storage is used to construct the block matrix, which is suitable for the construction of large tridiagonal block matrix.)

这是利用FFT分析相位差的程序，具有一定的参考价值！(This is done using FFT analysis phase of the program, has a certain reference value!)

C++实现的FFT，详细，简单，内含多个测试类(using C++ implements fft，including serials class)
