为感谢惠俊英老师的谆谆教诲，特为好奇诸君奉上水声物理--海洋传播声场模拟的一份武林秘籍！ 当好奇诸君阅毕此卷，再对照轻松跑完六份作业（六路招式），即入“水声物理”之江湖！ BELLHOP与AcousticsToolbox遵照GNU公共许可证进行分发。感谢Michael B. Porter对BELLHOP的原创，也感谢Orlando Camargo Rodríguez此份大道至简的入门秘籍。更感谢由Free Software凝聚起来的自由科学家社区。(Bellhop is a highly efficient ray tracing program, written in Fortran by Michael Porter as part of the Acoustic Toolbox (available at the website of the Ocean Acoustic Library). Bellhop is designed in order to perform two-dimensional acoustic ray tracing for a given sound speed profile c(z) or a given sound speed field c(r; z), in ocean waveguides with flat or variable absorbing boundaries. Output options include ray coordinates, travel time, amplitude, eigenrays, acoustic pressure or transmission loss (either coherent, incoherent or semi-coherent).)

给定很多数据点之后找这些类的聚类中心，然后重新分类。(Given after a lot of data points to find these kind of cluster center, and then reclassified.)

用于自学Matlab的一些小的简单的程序，里边涵盖了许多数学问题(For self-study a number of small simple Matlab program, covers a lot of math problems inside)

给出了用消元法解线性方程组的方法，消元法是解线性方程组有效地方法。(In this paper, the elimination method of solving linear equations, elimination method is effective method of solving linear equations.)

分别对正弦波，三角波，方波，一周期内取为整数的64个点（A=4095）；写锯齿波和方波的谐波构成（只写了3、4个）。(Of sine wave, triangle wave, square wave, A week off for integer in the period of 64 points (A = 4095) Write a sawtooth wave and square wave of harmonic (only wrote 3, 4).)
