set(gca,'xscale','log');
set(gca,'yscale','log');
set(gca,'zscale','log')
When I use the code, xlabel doesn't change with log scale.
I've used loglog, semilog but it doesn't work.

use the command
grid on
after plotting 3D function. Sometimes it is not visible clearly

These are meant for 2D plots only

Ran in:
[X,Y,Z] = peaks(50);
X = X - min(X(:)) + 1; % make it +ve for log
Y = Y - min(Y(:)) + 1;
Z = Z - min(Z(:)) + 1;
surf(X, Y, Z)
set(gca,'xscale','log');
set(gca,'yscale','log');
set(gca,'zscale','log')
