MATLAB 下的数字信号处理实现示例 附录一 信号、系统和系统响应 1、理想采样信号序列 （1）首先产生信号 x(n),0<=n<=50 (MATLAB under the realization of digital signal processing examples in Appendix 1 signal, systems and systems to respond to one, the ideal sampling signal sequence (1) First of all, have a signal x (n), 0 )

有限元 剖分------matlab 实现有限元四面体剖分(Finite element triangulation------ matlab finite element tetrahedralization)

matlab小程序，用来求趋势，很简单。主要是二次函数拟合趋势。(matlab small program used to find trends, very simple. The main trend is to fit a quadratic function.)

this is ECG r peak detection is given by this novel method.

the programs are an introduction to DSP ,the programs illustrate the frequency response ,impulse response and magnitude response

DTMF 的 matlab 仿 真 实 现(DTMF implementation of matlab simulation)

白噪声 –单位冲激信号 –正弦信号 –方波信号 –三角波信号 功率谱(White Noise- unit impulse signal- sinusoidal signal- a square wave signal- triangular wave signal power spectrum)

pCA的ppt报告，PCA理论，该理论可用于降维处理，将高维数据变化 为低维数据。(ppt Report of the PCA, PCA theory, the theory can be used to deal with dimensionality reduction, high dimensional data will change for the low-dimensional data.)

matlab 常用命令，如：hold on 用于保留当前图形和当前坐标轴属性，后面的图形命令只能在当前存在的坐标轴中增加图形，即设置当前坐标轴属性NexPlot为add，(matlab commonly used commands, such as: hold on to retain the current graphics and the current axes properties, behind the graphics commands only exist in the current axes to add graphics, or set the current axes properties NexPlot for the add,)
