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

Question

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?

Answer 1

% 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')
