How can I debug the error for generation of ECG Signals?

I tried executing the code which is attached below. It was downloaded from Mathworks.com. And the error seeen was:

Undefined function 'p_wav' for input arguments of type 'double'.

Error in complete (line 103)
pwav=p_wav(x,a_pwav,d_pwav,t_pwav,li);

Can anyone please explain me what does X= 0.01:0.01:2;and li=30/72 meant in coding of R.Karthik sir? Its very urgent.I am new to MAT LAB.

Shraddha - you need to download all of the files from Karthik Raviprakash's submission to the File Exchange. See the list of files from ECG simulation using MATLAB which includes the missing p_wav function that you require to avoid the above error. Just download the zip file, unpack it, and you should be able to execute the complete function.

Sir I am not able to execute even after unpacking the Zip file u have mentioned. Basically I am new to this whole Matlab, so can u please tell me exact method or steps to execute the same.

[Geoff Hayes]

Shraddah - are you still observing the same error, or is it something new? I downloaded the zip file and unpacked it. I then copied the matlab_codes folder to a folder on my workstation where I do MATLAB development. I launched MATLAB and, from the MATLAB Command Window, changed directory to matlab_codes. Within that directory, there should be seven files. I then ran

 >> complete

and I observed a signal.

[Shraddha Joshi]

OK Sir Thankyou so much I got the output signal

Hi Shraddha Im facing the same issue can you please tell me how you got the Output signal?
