I have:
k=2, 2.1, 2.2, 2.3, …, 4.9, 5.0
B=[0.2,0.4,0.6,0.8,1];
R=B/(1+k/2)
How to plot R like this: Thank you!

 Accepted Answer

R = B ./ ( 1 + k'/2 );
figure; plot( R )
or
R = bsxfun( @rdivide, B, ( 1 + k'/2 ) );
for earlier versions of Matlab that don't support implicit expansion

Thank you^^. But can you help the x-axis is k and Y is R?

Y is correct but X, k runs from 2:5 only, but in the graph, it is displayed 31 times of k

plot( k, R )
doc plot
gives details of different ways to parameterise plots.
If you just do
plot( R )
then it just uses indices along the x axis (i,e. 1 to 31 in your case). If you give it both an x and a y then it will plot both.
