Normalize x-axis and y-axis of surface plot
显示 更早的评论
I created a matlab code to calculate the cross ambiguity function. The results are correct, but the problem I am facing that the doppler and delay values are from 0 to 400, and the peak is centered at 200.
I am just wondering how can I normalize the x-axis (delay) and y-axis(doppler) of the surface plot to have the peak centered at 0?

Call surf with 3 inputs not just 1.
[x, y, z] = peaks;
figure
surf(z)
title('1 input')
figure
surf(x, y, z)
title('3 inputs')

Thanks!
I have one more question please.
Is there anyway to convert the surface plot (attached) to two plots; (X,Z) and (Y,Z)?
I'm only guessing what you mean by (X, Z) and (Y, Z) but perhaps changing the view of the axes may do what you're looking for?
makesurface % Default view
makesurface; view(0, 90) % x and y, looking down the z axis
makesurface; view(0, 0) % x and z, looking down the y axis
makesurface; view(90, 0) % y and z, looking down the x axis
function makesurface
figure
[x, y, z] = peaks;
surf(x, y, z);
xlabel('x')
ylabel('y')
zlabel('z');
end

I suspect you have matrices of x, y, and z data (like what was returned by the peaks function in my example above.)
[x, y, z] = peaks;
whos
So what specifically do you mean by "plot the X-axis with Z-axis"? For the peaks data, what do you want to plot? Do you want to turn them into a vector?
plot(x(:), y(:))
figure
plot(x(:), z(:))
figure
plot(y(:), z(:))
Or do you want the view-based approach I showed earlier? Or did you have something else in mind?
