I want to display the frequency scale ( 0:1:10 ) on y-axis for the following code:

   x=peaks;
    f=10; % freq 
    fval=0:1:f;
    mesh(x)
    set(gca,'Ydir','reverse')
    ylabel('freq. Hz')
    xlabel('Samples')
    zlabel('Amp.')

This works:

x=peaks;
f=10; % freq
fval=0:1:f;
mesh(x)
set(gca,'Ydir','reverse')
ylabel('freq. Hz')
xlabel('Samples')
zlabel('Amp.')
yt = get(gca,'YLim');                                                       % Get Y-Limits Values
dyt = 0:10;                                                                 % Desired Y-Tick Values
set(gca, 'YTick',linspace(min(yt),max(yt),length(dyt)), 'YTickLabel', dyt)  % Set New Labels
