数学建模的钻井布局题解决的源代码，包括矩阵的映射，井的覆盖范围的叠加等等代码(Mathematical modeling of drilling to solve the layout problem of the source code, including the matrix of the mapping, the coverage of well superimposed code etc.)

This is dialog program. for use playing the music through the serial interface. So, this program is included RS-232.

Intermodulation or intermodulation distortion (IMD) is the amplitude modulation of signals containing two or more different frequencies in a system with nonlinearities. The intermodulation between each frequency component will form additional signals at frequencies that are not just at harmonic frequencies (integer multiples) of either, but also at the sum and difference frequencies of the original frequencies and at multiples of those sum and difference frequencies.

历届数学建模大赛的MATLAB的M文件，较为齐全。(Past mathematical modeling contest MATLAB M-files is complete.)

本程序基于Matlab，可以对特定波长光线在透镜系统中进行光线追迹。可以生成任意方向平行光，点光源任意角度光线，并对全反射，光线射出系统等特殊情况用红色标出。透镜数任意，透镜参数可设。(The program is based on Matlab, with a specific wavelength of light in the lens system for ray tracing. Parallel light can be generated in any direction, at any angle point source of light, and the reflection of light injection system and other special circumstances marked in red. Any number of lenses, lens parameters can be set.)
