I have a dataset of MIT-BIH Arrhythmia Database

i want to load the data and display the ECG signal,I tried using laod command but error message is displayed

please assist

Read your post from our point of view. Have you given us enough information to help you? Why was MIT (I guess who gave you the data) not able to help you?

I need to solve a problem from a field that's somewhat unrelated to this forum. I won't tell you what the problem is, but please guess some solutions for me.

What sort of data is the MIT-BIH database? Is it text? Is it binary? It doesn't sound like a format Matlab is familiar with. Please be more specific.

Sorry everyone,here is the link to it ,it consist of dat,hea,atr files

itis a signal of ECG wave,i want to load and sisplay the ECG wave form

This and this page tell you how to install the database to look at the data. Have you tried that?

No actually i want to load and display it

Then you need to know how the database is organized and transform the binary data to import it to Matlab. That's an awful lot of work I'm afraid. Alternatively, you could install the database, as suggested, and then find a way to transfer that to Matlab. Still some work would be needed.

This is not going to happen automagically.

Alternatively, someone may have already dealt with this problem. So I would suggest you look in the File Exchange, or ask others in your lab/uni/place of work, or contact the people that generated the data.

@FIR: Obviously the files are not written in Matlab's MAT file format. Therefore LOAD must fail. The authors of the cited papers and of the program have detailed knowledge about the used format, so it is most efficient to ask them at first.
