Question

I have been provided around 3600 different numbers between 500 and 1300. I need to code using MATLAB in order to plot these numbers as an ECG monitor. can you help?

thanks

the data sample has been read from an ecg sensor,

has been digitised at 360 samples per second.

11 bit resolution over mV range. it says to plot the peaks. the steps are

frequency domain analysis

filter design and fvtool analysis

Answer 1

figure(1)

subplot(1,2,1)

x=[1300:3600]

y=[1300,3600]

L=strsplit(sprintf('%.1f,%.1f)/n' , [x(:) y(:)], '/n');

plot(x,y, '+r')

text(x,y,L(1:length(x)) , 'HorizontalAlignment' , 'center' , 'verticalAlignment' , 'bottom')

axis([1300 3600 1300 3600])

sublpot(1,2,2)

x=(1300 3600)

y=[1300,3600]

L=strsplit(sprintf('%.1f,%.1f)/n' , [x(:) y(:)], '/n');

plot(x,y, '+r')

text(x,y,L(1:length(x)) , 'HorizontalAlignment' , 'center' , 'verticalAlignment' , 'bottom')

axis([1300 3600 1300 3600])
