(0,3.8*10^8)
(1,4.2*10^7)
(2,1.5*10^7)
(3,7.8*10^7)
(4,4.7*10^6)
(5,3.16*10^6)
(6,2.3*10^6)
(7,1.7*10^6)

Hi Brian Len,
you might have some troubles with syntax. Have a look at the very good documentation: https://de.mathworks.com/help/matlab/language-fundamentals.html
dInput = [0,3.8e8;
1,4.2e7;
2,1.5e7;
3,7.8e7;
4,4.7e6;
5,3.16e6;
6,2.3e6;
7,1.7e6;
8,1.3e6;
9,1.05e6;
10,8.66e5];
fh = figure;
ah = axes(fh);
hold(ah,'on');
plot(ah,dInput(:,1),dInput(:,2),'.')
Kind regards,
Robert
