MATLAB 下的数字信号处理实现示例 包括: 单位脉冲序列 矩形序列 特定冲击串 卷积计算 卷积定律验证 (MATLAB under the realization of digital signal processing examples include: unit rectangular pulse sequence sequence-specific impact of the law of string convolution convolution calculation to verify)

一个圆周卷积的代码~调用形式为y=juanji(h,x1,M) 其中，h和x1为输入，h为滤波器系数，x1为输入采样信号，输出为y,M为输入信号x1的长度。(A circular convolution of the code to call the form of y = juanji (h, x1, M) of them, h, and x1 for the input, h for the filter coefficient, x1 sampling input signals, output y, M for the input signal x1 length.)

说明：  利用EM算法对非线性状态空间模型参数估计，效果良好(The EM algorithm is used to estimate the parameters of the non-linear state space model with good results.)

好不容易找到的matlab的时频分析工具箱，添加的方法不说了，里面的工具很全，挺好用的，希望对大家有帮助。(Finally found the time-frequency analysis matlab toolbox, adding that the method, which is full of tools, very good use, and would like to help everyone.)

用BP网络完成函数的逼近 P网络通常有一个或多个隐层，隐层中的神经元均采用sigmoid型变换函数，输出层的神经元采用纯线性变换函数。本例应用一个两层BP网络来完成函数逼近的任务，其中隐层的神经元个数是5。(network to be completed by BP function approximation P networks usually have one or more hidden layer, a hidden layer neurons are used sigmoid-type transformation function, the output layer neurons using pure linear transformation function. The application of a two-tier cases BP network function approximation to complete the task, hidden layer neuron number is 5.)

用newmark-beta法计算单自由度结构输入地震动后的位移时程曲线，该函数可应用于各种周期的结构的反应，不存在中心差分法的问题 (newmark-beta method)
