Reverse the X and Y axis values in a 3D plot

I have used below code to plot a 3D plot.

f1=2 ; f2=1.8 ; .... ....

Pt=0:5:30;

A1=2*pi*del*f1*f1*Vt*Vt*10^18; A2=2*pi*del*f2*f2*Vt*Vt*10^18; .... ....

B=c^2*Pt*s*t;

K1=(A1./B)./10; K2=(A2./B)./10; .... ....

f11=[f1;f2;f3;f4;f5;f6;f7;f8;f9;f10]; K=[K10;K9;K8;K7;K6;K5;K4;K3;K2;K1]; Pt=[Pt;Pt;Pt;Pt;Pt;Pt;Pt;Pt;Pt;Pt];

figure,surf(Pt,f11,K);

In the 3D plot I need to reverse the X-axis (f) and Y-axis (K) values in reverse order.

Could you please tell me how to do it?

% An example:

[X,Y,Z] = peaks(30);
surfc(X,Y,Z)
colormap hsv
axis([-3 3 -3 3 -10 5])

% Reverse x and y axis

set(gca,'Xdir','reverse','Ydir','reverse')

doc flipud
doc fliplr

flip the data using one of the above.

maybe:

%Get the current axes data, flip it and set it
set(gca,'xdata',fliplr(get(gca,'xdata')))

I have modified the last lines as below.

set(gca,'f11',fliplr(get(gca,'f11')))

set(gca,'K',fliplr(get(gca,'K')))

figure,surf(Pt,f11,K);

But I got the below error.

There is no 'f11' property in the 'axes' class.

Error in ==> t2 at 88

set(gca,'f11',fliplr(get(gca,'f11')))

Could you please help.

fll would be the axes' 'ydata'.. axes doesnt; care what it was the variable called before.

[ravi]

I have changed as below.

set(gca,'ydata',fliplr(get(gca,'ydata')))

But still got the similar error.

??? There is no 'ydata' property in the 'axes' class.

[Sean de Wolski]

My bad, that does error. Try this:

h = surf(magic(5));

pause(5); %look around

set(h,'ydata',flipud(get(h,'ydata')))

drawnow;
