谱分析的源程序，适合通信等专业的初学者学习使用，希望给需要的人帮助(Spectral analysis of the source, suitable for beginners to learn communication and other professional use, I hope to those who need help)

一个拟合椭圆的程序，采用matlab编程，利用均值误差作为代价函数。(A fitting elliptical procedures, the use of matlab programming, using the mean error as the cost function.)

说明：  可根据需要一步步生成三变量或者四变量的卡诺图！谢谢！(To make kanuotu!)

Good file to test for nothing.

常规地震假设地下介质是各项同性的，但实际上，是各向异性的。各向异性介质的反射系数随入射角、方位角不同而不同。(Reflection coefficient varies with incident angle and azimuthal angle.)

说明：  一些MATLAB的学习资料，我个人觉得还挺有用，希望能对大家有所帮助！(Some MATLAB-learning materials, I personally think that' s kinda useful, hope you can help!)

使用matlab产生线性调频信号，并进行脉冲压缩处理。(Use matlab to produce linear FM signal, and pulse compression processing.)
