Hi friends, How can I plot a 3D surface plot or 3D mesh from this kind of data in matlab. Column1 on X axis, column2 on Y axis and column3 on Z axis.
h = [ 100 100 0.0243 ; 100 310 0.0679 ; 100 350 0.0643 ;
150 200 0.3153 ;
150 250 0.3010 ;
150 450 0.1087 ;
200 180 0.4895 ;
200 400 0.1529 ;
200 450 0.1123 ; ];
I already used plot3() command but get discretely plotted values, not a surface plot or mesh.
Thanks, Yusuf

You could feed the unique values of the first two columns into meshgrid() to get a uniform grid, then with reshaping the third column accordingly you can use mesh() or surf().
