the variable is a array
I want x sclae from -2600 to 2500(gettable)
y scale as 0:4:40 (how to code this)
z scale in logarithmic form.
if true
% code
load('Kennfeld1.mat');
surf(Kennfeld1);
xlabel ('Achsemoment (N)');ylabel ('Diffrenz Drehzahl (rpm)');zlabel ('Zeit (std)');title('Vorderräder');

load('Kennfeld1.mat');
h=gca
surf(Kennfeld1);
xlabel ('Achsemoment (N)');ylabel ('Diffrenz Drehzahl (rpm)');
zlabel ('Zeit (std)');
title('Vorderräder');
set(h,'zscale','log')

see the graph attached z axis is represented in logscale
What is ' h = gca' what do these mean?

'h = gca' just allows you to access the settings for the axis (gca stands for "get current axis") by typing h. It's not really necessary when you're also using set(); you could just do set(gca, ...).
