Matlab Code for the graph

How can i obtain this graph using code?

[Geoff Hayes]

Barry Allen! Do you have an equation for the maximum throughput ofr spectrum sensing? Presumably the inputs are duration and Pa.

[Barry Allen]

I have worked hard about this and cant even know how to obtain the simulations with the equations.I even changed some of the equations into codes but still no result.I had attached the paper for your reference if possible please let me know about how to proceed in it.

[Barry Allen]

The equation is

and I will attach the paper here

Barry - you may want to contact the author of the paper or discuss this with your professor. I'm assuming that this is for a school project (?).

[Barry Allen]

Yes it is for college project and my professor dont have a lot of knowledge in that field .How can i contact the author?

I have tried but no response:(

In this case, it would be fastest to use your ruler to get some of the X and Y points for the three Pa curves. Store them in Matlab vectors. Then run an smoothing operation if needed.

x = [0.1 0.4 0.7 0.9]; % you can add more points if needed
% my eyballing the plot without ruller
Pa5m = [0.25 1.5 1.25 0.25];
Pa10m = [0.6 2 1.5 0.25];
Pa20m = [1.2 2.5 1.75 0.25];
xq = 0.1:0.05:0.9;
Pa5m = interp1(x,Pa5m,xq,'spline');
Pa10m = interp1(x,Pa10m,xq,'spline');
Pa20m = interp1(x,Pa20m,xq,'spline');

The rest of the plotting is straight forward once you have them in vector form. There are also other options for interpolation method that may work better for your problem.
