How to Plot 3D Surface in Matlab Using meshgrid, logspace, and surf Functions?

here is the matlab program, when i run it, i m not getting the required result. So if u have any information about it, help me.
here is the coding for it.
x=linspace(0,14,6);
y=logspace(-2,4,6);
[x y] = meshgrid(x, y );
z = x.^2 + y.^.6;
set(gca,'YScale','log','ZLim',[0 3])
surf(z);
xlabel('Number of required channels')
ylabel('Arrival rate (arrivals/sec)')
zlabel('Interference ratio of interference to the macrocell, R_I_F_M')
The graph i want to get is given in image. plz help me..

What is the function to plot?

[x y] = meshgrid(x, y ); z = x.2 + y..6; set(gca,‘YScale’,‘log’,‘ZLim’,[0 3])

i think that you forget the commas in the [x, y]

Yes I think so, I just plotted it looks like the image sort of.

i get this graph from a file whose topic is

"Interference Analysis and Mitigation for Cognitive-Empowered Femtocells Through Stochastic Dual Control"

I wanna snd u the file, but couldnt. I dint know why, but it stops moving on n give error

the language of matlab following line by line what you programmed. If the graph starts to build, because every line is everything is right. When he is in because somewhere, have some small error such as failing to put a comma, or because you put something bigger in error. In Matlab and other programming languages ​​is common brackets you put commas separating the variables. For example, in bracket [x y] you should place [x, y]. can show that the bracket is set, or a function. And always have to have an explanation for the computer to understand. It reads that the [bracket] is set X and Y together Or is there other symbols that you use to indicate that there are two sets, the set x and y together. have for example in some languages ​​[x .. y] do not indicate that there is both sets but indicates that values ​​ranges from x to y. For example if I had a straight 2-14 and I want to use only a few numbers I write [3 .. 10] The program will understand what you're asking, 3, 4, 5, 6, 7, 8, 9, 10.
without it the program will not understand anything, he will see [xy] or better if you put [3 10] it will only understand numbers 3 and 10. and then will not do anything with it. You need to give the equation numbers you chose and that case with this error only he will understand the two numbers.

after corrected the lack of signs or commas range. And you keep giving me error alerts by email and I try to understand the equation and try to fix it for you. Sometimes it happens that books put the equations missing characters. Understand that happens typographical errors.
