How to draw a surface in matlab as Y is not fixed? Help!!!

Question: How to draw a surface in matlab as Y is not fixed?
X = [1, 2, 3, 4, 5]
As x=1, Y=[4.8, 4.9, 5.0]
As x=2, Y=[4.6, 4.8,5.0]
As x=3, Y=[4.3, 4.7,5.0]
As x=4, Y=[4, 4.5, 5.0]
As x=5, Y=[3.8,4.4,5.0]
So here Y always has 3 elements, but the range of Y is changing as x increases.

Z is function of x and y, and it’s a 3*5 matrix. We already have the value of each z element.

How could I draw a surface plot in XYZ coordinate system in Matlab?

Thanks a lot!

The trick is to have vectors and matrices in correct row-column form.
I tried this

X=1:5;
Y(1,:)=[4.8, 4.9, 5.0];
Y(2,:)=[4.6, 4.8, 5.0];
Y(3,:)=[4.3, 4.7, 5.0];
Y(4,:)=[4  , 4.5, 5.0];
Y(5,:)=[3.8, 4.4, 5.0];
Z=rand(3,5); % to simulate your function
surf(X,Y',Z)

I hope this helps!
