Help with 3D plot and meshgrid

I have a meshgrid of variables X and Y defined as

x=[-25:0.5:24.5];
y=[-25:0.5:24.5];
[X,Y]=meshgrid(x,y);

and have a vector of 10,000 data points, called W.

I would like to make a 3D plot of the data points along x and y. The data points need to be plotted at x and y locations as illustrated below:

Data point 1: x = -25 y = -25

Data point 2: x = -25 y = -24.5

Data point 3: x = -25 y = -24

...

Data point 100: x = -25 y = 24.5

Data point 101: x = -24.5 y = -25

Data point 102: x = -24.5 y = -24.5

...

Data point 200: x = -24.5 y = 24.5

...

Data point 10000: x = 24.5 y = 24.5

Thanks for your help.

I am using MATLAB R2012a.

You could use the reshape command to turn your matrix v into one with the same size as your mesh, then plot using a command like surface, plot3, or scatter3

x = [-25:0.5:24.5];
y = [-25:0.5:24.5];
[X,Y] = meshgrid(x,y);
v = 1:10000;
v = reshape(v,size(X,1),size(X,2));
surface(X,Y,v)
