How do I ajust the vallues the X-axis of a mesh (Z,Y,X) plot?

Hello,
I have a mesh(Z) plot that looks perfect, I just need to adjust the values of only the x axis (1 to 132) to (0.0216 to 0.9524 in 132 steps) I have put these new x-values in a 1 x 132 vector called Residue_ratio.
Any help? I tried using
mesh(z,,Residu_ratio)
but this seems to be wrong input arguments. I have also tried
set(gca,'XTick'
but matlab does not seem to recognize this code.
Thanks
Tim

hi, adjust this example to your needs:
[X,Y] = meshgrid(-8:.5:8);
R = sqrt(X.^2 + Y.^2) + eps;
Z = sin(R)./R;
figure
mesh(Z)
xlabel('X')
x_ticks = linspace(0,40,41);
set(gca,'XTick',x_ticks)

mesh(Residue_ratio, 1:size(Z,2), Z)

That's correct. The mesh function wants either Z or X,Y,Z. It doesn't have an option where you can give an X & Z but omit the Y.
