一些典型的DSP程序，对初学者比较有帮助，主要结合Digital Signal Processing——A Computer-based（电子工业出版社）一书课后题目编写。 (Some typical DSP program, the more help for beginners, mainly with Digital Signal Processing——A Computer-based. )

在matlab中用delaunay函数实现三角剖分，在一个三角形区域内，实现简单的均匀的delaunay剖分。(In matlab function implementation using delaunay triangulation, in the area of ​ ​ a triangle, a simple uniform delaunay triangulation.)

说明：  在matlab中直接运行程序，将会显示包含谐波的时域、频域图，设计一个滤波器，滤除谐波，得到滤除谐波后的图形。(Run the program directly in matlab will display a harmonic of the time domain, frequency domain, to design a filter, harmonic filter, harmonic filter obtained after the graphics.)

This code is NUMBER1: MATLAB code for paper: calculation of electron energies in a quantum well using the transfer matrix method. we solve the time independent schrodinger equation in 1D AlGaAs/GaAs/AlGaAs quantum well using the transfer matrix method. We define a wave function for each point of well and barriers and convert it to a 2in2 matrix. Multiplying of matrixes with boundary conditions results in discrete energies and their wave functions. We compare our results with other simulations and calculate discrete energies for different wells.
