I use
plot3(x,y,z, 'b')
box on
for plotting a 3D system. I want the faces of xy-plane, yz-plane and zx-plane to be colored by blue, red and white respectively.
Please suggest me the code. Thanks in advance.

You can determine the axis sizes by get(gca, 'XLim') and YLim and ZLim. Using those values, you can create patch() objects that are rectangles in 3-space with the colors you want.

Thanks for your reply. I am not able to solve the issue. Here I am giving the code
u=linspace(0.75,1.25,51);
v=linspace(-1.25,-0.75,51);
[x,y]=meshgrid(u,v);
z1=y.*exp(x.^2);
mesh(x,y,z1)
xlabel('x'),ylabel('y'),zlabel('z')
title('3D Example with different domains')
hold on; box on;
z2=x.^2./y;
mesh(x,y,z2)
hold off
Please make my xy-plane colored only.

XL = get(gca, 'XLim');
YL = get(gca, 'YLim');
patch([XL(1), XL(2), XL(2), XL(1)], [YL(1), YL(1), YL(2), YL(2)], [0 0 0 0 0], 'FaceColor', [0 1 0]);

typo: there is a 5th 0 in your Z vector that you do not need
