x = 10:0.05:30;
z = 1:0.005:3;
[X,Z] = ndgrid(x,z);
mesh(X,Z,Y)
This is the plotting code, however the surface i got does not scale accordingly. It gives a scale of equal length for x and z instead of having z shorter and x longer. How do i adjust this such that the plot actually shows that the length of z axis is e.g 2 while length of x axis is a longer 20.

can be used to control the aspect ratio of the plotting area and the data.
Also
axis equal
will set the true [1 1 1] aspect ratio.

i tried axis equal but it changes the Y variable axis as well, how do i set for only x and z to be true[1 1] such that the Y variable axis still remains the same as before

You need to use one of the two functions I mentioned first to give more specific control over the aspect ratios.
