sampencandApEn.m 为证明 样本熵 较 近似熵 更准确的程序 fast_ApEn1.m sampenc.m 为sampencandApEn.m的子程序(sampencandApEn.m sample entropy to prove more accurate than the approximate entropy procedure 3.fast_ApEn1.m sampenc.m subroutine is sampencandApEn.m)

signal+noise is very simple like this

说明：  the linear ARX model as shown below [12] is used to represent the input and the output data for the system. This ARX model is utilized for both Least Square (LS) and Recursive Least Square (RLS) algorithms. It is one of the simplest statistical methods for system identification used to find the transfer function for the model. The equations given by [15]: Y=φβ+ξ (7) β=〖(φ^T φ)〗^(-1) φ^T Y (8) where Y is the predicted output. φ is includes actual input and output parameters. β is includes parameters to be estimated.
