How do i plot and label a graph using secondary axis in matlab

Hello, I'm trying to plot and label two vertical axes for (A and B) of different scales against the same horizontal axis (U).

U=[1 2 3 4 5 6 7 8];
A=[0.0141  0.0135  0.013  0.0125  0.012  0.0117  0.0113  0.011];
B=[0.142267  0.14271177  0.1430866  0.14334375  0.14357196  0.143885125  0.144042862  0.14423808];

U=[1 2 3 4 5 6 7 8];
A=[0.0141  0.0135  0.013  0.0125  0.012  0.0117  0.0113  0.011];
B=[0.142267  0.14271177  0.1430866  0.14334375  0.14357196  0.143885125  0.144042862  0.14423808];

yyaxis left
plot(U,A)
yyaxis right
plot(U,B)

If you're on an older release without yyaxis, then look at plotyy or upgrade.
