How to plot meshgrid without successive intervals

Respected sir,

My data set is X=1,1.5,2,2.5,3

Y=0.8351,0.8265,0.7569,0.6348,0.5219

X=[1,1.5,2,2.5,3] ; 
Y=[0.8351,0.8265,0.7569,0.6348,0.5219] ; 
[X,Y] = meshgrid(X,Y) ;
plot(X,Y,'r',X',Y','r')

I need mesh or surf figure for this data set.

Already X, Y is a mesh.

X=[1,1.5,2,2.5,3] ; 
Y=[0.8351,0.8265,0.7569,0.6348,0.5219] ; 
[X,Y] = meshgrid(X,Y) ;
Z = sqrt(X.^2+Y.^2) ; 
figure
surf(X,Y,Z)
figure
mesh(X,Y)
