How to separate two signal?

Two signals are plotted on same figure as shown below. One signal is plotted in green color and the other one is in blue.

I need to plot them separately.

The code I used to plot above signal is:

 plotATM('16786m')

Source files are available to download here

These signals are of ECG and taken from PhysioNet Database .

I am getting error i.e. Undefined function or variable 'val'.

I am using older version of MATLAB. It's MATLAB R2013a

'val' function does not work in MATLAB rather it works in MuPAD and I don't know how to use MuPAD.
