select 20 percent between two values
显示 更早的评论
Hi All,
I have a lot of recordings to anlyze, but not enough time to go through the whole of them. Now I would like MATLAB to randomly select 20% of each recording. So what I want in the end is to create a function, that I can set my directory to all the recordings, and than for each 20% percent is randomly selected and put into a new wav. file that I can use for the analyses. I looked at examples of random sampling, but could not find anything like this. Is this possible to do in MATLAB?
Cheers,
Simone

% recordingList is an array that contains all of your recordings.
randIdx = randsample(numel(recordingList), round(numel(recordingList)*.2));
sample = recordingList(randIdx);
