Plot a Mesh or Surf plot for data points without a function

I need to make a mesh plot/ surf plot for the following data

X = [1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5];

Y = [1, 0.9, 0.8, 0.7, 0.6, 0.5, 0.4, 0.3, 0.2, 0.1];

Z = [103, 120, 156, 206, 256, 302, 342, 376, 448, 508];

How can I plot a 3D mesh/surf plot for this data wherein X and Y are giving rise to the data poins in Z?

Thank you.

(X,Y) is a striaght line..how you expect a surf plot?

Can you suggest how this can be plotted in 3D, I have tried plot3 and it comes out well, but is there a way to plot it in imagesc or mesh?

It is a curve/ line ....you can make it a mesh...

Forget about how to write code for a moment and think of this problem conceptually.

You've got 3 variables that define 10 points in a 3D space. When those 10 points are connected, it forms a line / curve which is what you see when you plot the variables with plot3.

It's unclear to us how those data can be extended to illustrate a surface. If Z were a matrix of size (numel(X), numel(Y)), then you could use meshgrid or ndgrid to expand the X and Y values in order to plot a surface.
