Running longer recording

[preethik...@gmail.com]

I am using the Matlab second example to run a longer recording (30min) from Physionet MIT BIH database. When I look at the mat files I see only a smaller file.

Anyone on this forum, who can tell me how I can save the entire result for 30 minutes.

Thanks,

Preethi

Dear Preethi, please attach an example of what you are trying to do in order to reproduce your problem, the output you obtain (command window, screen capture, etc), and your installation details.

Best,

M,.

Thank you for your response. I read the documentation and I hope I did not miss anything.

I am running the same file 201m.mat using 1st example and 2nd example. I saw that the mat files for 2nd example is smaller. I am using Matlab 2018a version. Please see attached screenshot for data and results. I am unable to attach text files, so I will copy paste the command window results below .
