MATLAB: How to plot the curve

Question

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!

Answer 1

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
