Here is my code
function [] = plotFile(heartRate,titleName,beats,dt)

%This function is to be used with FILENAME and will display inputs
%vs. the outputs in the first figure. In the second figure, an ECG of the
%first instance of the input file will be displayed.

%%Plot ECG Signal
heartRate = heartRate(1,1);
