本文使用小波分析中的Mallat 算法和圖形顯示算法相結合的方法，成功的去除了脈
搏波中的呼吸干擾。采用Matlab Builder for .NET，將用于脈搏波去噪的M 文件轉換為COM組件，然后在VB 中調用該組件，開發出脈搏波去噪軟件。該軟件完全脫離了Matlab 開發環境，且發布過程簡單。利用此方法顯著的減少了軟件開發時的工作量, 提高了軟件的開發效率、質量以及核心算法的保密性。

Using Matlab Builder for. NET, convert the pulse wave denoising M documents into COM component, and then to invoke the component in VB and develope the pulse wave denoising software. The software is entirely out of the Matlab software environment, and the release process is very simple. This method can remarkably relieve the workload and make it more efficient while developing software, and improve the quality, as well as the security of the core algorithm.
