How to plot the curve?

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

[Adam]

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

[Adam]

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.
