回归的各种分析实例以及matlab代码，包括各种数学应用，比如线性回归，非线性回归，逐步回归(Examples of regression analysis, as well as a variety of matlab code, including a variety of mathematical applications such as linear regression, nonlinear regression, stepwise regression)

正交频分复用其主要思想是：将信道分成若干正交子信道，将高速数据信号转换成并行的低速子数据流，调制到在每个子信道上进行传输。正交信号可以通过在接收端采用相关技术来分开，这样可以减少子信道之间的相互干扰 ICI 。(Orthogonal Frequency Division Multiplexing)

说明：  差分进化算法(Differential Evolution Algorithm，DE)是一种高效的全局优化算法。它也是基于群体的启发式搜索算法，群中的每个个体对应一个解向量。差分进化算法的进化流程则与遗传算法非常类似，都包括变异、杂交和选择操作，但这些操作的具体定义与遗传算法有所不同(Differential evolution algorithm (DE) is an efficient global optimization algorithm. It is also a heuristic search algorithm based on population. Each individual in the group corresponds to a solution vector. The evolution process of differential evolution algorithm is very similar to genetic algorithm, including mutation, hybridization and selection operations, but the specific definition of these operations is different from that of genetic algorithm)

空气中声传播的fdtd例程，简单可用，希望对大家有帮助(Fdtd airborne sound propagation routines, simply available, we hope to help)

一个使用数学方法生成波形声音文件的源代码，可以载入预置数学公式，保存8位和16位单声道声音文件，可以设置振幅、频率、持续、采样等参数，可以调整波形斜面，回声。 这个代码值得推荐！(The use of mathematical methods to generate a waveform sound files of source code, can load preset mathematical formula, save 8 and 16-bit mono sound files, you can set the amplitude, frequency, continuous, sampling and other parameters, you can adjust waveform slope, echo . It is recommended this code!)
