I am trying to create "mesh" (surf) out of 2D matrix which is changing by time on its values
x = 1:30;
y = x;
Z = [ 1 1 1; 1 1 1; 1 1 1];
[X30 , Y30] = meshgrid(x,y);
a=1;
for inc = 1:30
Z30 = imresize (Z,[30 30],'bicubic');
a = a + 1;
Z(2,2) = a;
surf(X30,Y30,Z30)
axis([0 30 0 30 0 30])
pause(0.5)
end
The "surf" shows plot with "auto" axis limitation and after applying "axis" function are the size limited, so I have two plots refreshed subsequently - can be set the axis of surf once?

Each time you call the surf function, you get a brand new axes. This means any settings set in the previous axes are lost, and must be reset.
It looks like you just want to update the Z values of your surface. You can do that by accessing the ZData property of your plot. Try this.
x = 1:30;
[X30 , Y30] = meshgrid(x);
Z = [ 1 1 1; 1 1 1; 1 1 1];
Z30 = imresize (Z,[30 30],'bicubic');
sf = surf(X30,Y30,Z30);
axis([0 30 0 30 0 30])
for a = 1:30
Z(2,2) = a;
Z30 = imresize (Z,[30 30],'bicubic');
sf.ZData = Z30;
pause(0.5)
end

Look into the options available in the axis command, in particular the 'style' options.
I don't understand the rest of yoru questions, but they appear to be more about app designer, so I would suggest starting a new question for that.

That's correct. It's about the AppDesigner.
