I have a ECG signal along with a respiration signal, I need to filter it to separate the ECG and the Respiration signals. I can apply a FIR/IIR filter or any appropriate method. Also, i need to extract the QRS complex from the filtered ECG. I have attachted the code that I use to filter the signal extract the QRS complex but the results are not satisfying.

I think this example will help you get started. I would also recommend looking at the findpeaks function. Looking at the File Exchange, here are one, two, and three submissions that seems relevant to the work you're doing.
