@sai lakshmi,

sorry if my request was vague. What I was asking for is an image of what your data looks like when visualized/plotted. Here's an unrelated example I pulled from the internet, below but even this image lacks critical information such as axis labels.

Remember that we are working in the dark so in order to maximize the help you get from volunteers here, you need to provide us with enough information to develop a mental image of your problem before we can think of a solution. A picture is worth 1000 words (plus the 300+ words already included in comments above) so if we can see what kind of peaks you're working with, your axis limits, the range of values within your data, the scale of your data, etc, we will be much better equipt to think of solutions.

This phrase "ecg signal for 300 qrs complexes of MIT_BIH atrial fibrillation database" tells us virtually nothing - even if we are familiar with ecg signals. Our best chances to help you would require a lot of time searching the internet to figure out what that database is - and why would we do that?

So, as a mini lesson, keep in mind the need to define a solid question that contains all the background information needed and requires less than 1 minute to read and understand.

Was the code the exact code from that exact paper that he wants to implement?

sai, if you can't code up the paper, then the Mathworks consulting group can do it for you.

It was never clear that this paper was a requirement. The example I suggested will provide him the locations of the QRS peaks. To me it appeared that he found a paper that did what he wanted, but their method was quite complicated, and I thought I would give him an alternative, simpler approach.

Sai, if you are specifically trying to reproduce the works of this paper, I can only agree with Image Analyst in regards to looking into a consulting option.
