transport model of ground water with breakdown curve in matlab

介绍了两种汽车纵向动力学整车模型，包括制动跟油门控制，希望对大家有用(Introduces two vehicle longitudinal vehicle dynamics models, including brake with throttle control, we hope to be useful)

说明：  双音频按键识别 背景： 打电话拨号时，每次按键会发出不同的声音，这些声音实际上是由一些固定频率的正弦信号合成的。因为每个按键声音包含两个不同频率的正弦信号，因此也被称为“双音频”信号，简记为DTMF。这相当于是对不同键位用‘音频’进行了编码，如同计算机领域中用数字0和1对处理对象（包括键盘）进行编码。(Two-tone buttons identify Background: When you call dial, each key emits different sounds, which is actually made up of some fixed frequency sinusoidal signal synthesis. Because the sound of each key contains two sinusoidal signals of different frequencies, it is also known as &quot two-tone&quot signal, abbreviated as DTMF. This is equivalent to different keys using the ' audio' encoded, as the computer industry with the numbers 0 and 1 pair of processing object (including the keyboard) to be encoded.)

说明：  MATLAB编写的有关数学问题的数学函数优化程序，即求函数极值问题的相关程序(MATLAB solving physics problems of extreme values with mathematics)

平滑LMS自适应滤波器，实现信号的自适应滤波作用。(Smooth LMS adaptive filter, adaptive filtering effect the signals.)

采用matlab实现了GPS单点定位，包括读Ｎ文件、O文件，定位解算，坐标转换等。(Matlab achieved using GPS single point positioning, including the reading of N documents, O file, locate solver, coordinate conversion.)
