半正定矩阵cholesky方法将其分解为两个上下三角矩阵相乘的形式。matlab自带的函数只能分解正定矩阵。并且给出例子。(Semi-definite matrix cholesky method be decomposed into two upper and lower triangular matrices form. matlab built-in function can only be positive definite matrix decomposition.)

经验模态分解方法简称EMD方法。该方法从本质上讲是对一个信号进行平稳化处理，其结果是将信号中真实存在的不同尺度波动或趋势逐级分解开来，产生一系列具有不同特征尺度的数据序列。(Empirical mode decomposition method is referred to as the EMD method. This method is in essence a signal smoothing processing, the result is the real signal different scales swings or trends gradual decomposition open, resulting in a series of a data sequence having a different characteristic scale.)

说明：  分析信号的系统响应的实验代码，附有详细的实验说明和源代码，并对实验现象进行解释(Analysis of the signal system in response to the experimental code, with detailed experimental descriptions and source code, and to explain experimental phenomena)

利用 MATLAB 实现窗函数法设计 FIR 滤波器，主要是选择合适的窗函 数进行截断运算 (Window function method using MATLAB to design FIR filter, main is to choose the appropriate letter for window blocking operations.First theoretically to approximate the unit impulse response of ideal filter hd [k], to be determined by the passband and stopband attenuation index window function types, determined by transition zone FIR filter order M length (or N), and finally USES MATLAB to calculate the window function value, and hd wN [k] [k] value, so that the design of FIR filter h (k) MATLAB provides the blackman window function is: w = blackman (N) Where N is the length of the window function.)
