在MATLAB Signal Processing Toolbox中取消findpeaks警告 [英] suppress findpeaks warnings in MATLAB Signal Processing Toolbox

问题描述

我使用了MATLAB信号处理工具箱中的函数 findpeaks .但是每次该函数找不到任何峰值时，我都会收到警告:

I use the function findpeaks from MATLAB's Signal Processing Toolbox. But everytime the function does not find any peaks I receive the warning:

Warning: No peaks found. 
> In findpeaks at 83

现在我还是要处理这些情况，因此请检查findpeaks返回的向量是否为空.因此，我想禁止显示这些警告，因为我不希望我的命令窗口变得混乱.

Now I have to handle those cases anyway and therefore check if the vector returned by findpeaks is empty. So I would like to suppress those warnings, because I don't want my Command Window to get cluttered up.

推荐答案

首先确定警告ID:

findpeaks([1 1 1 1 ]);
[msg id] = lastwarn;

然后关闭警告:

warning('off',id)
