I am having the matrix k where each row represents a 3dimensional point.Each column of the matrix represents the respective dimensional value of each point.How can i make the 3d surface for the matrix?Kindly need help as soon as possible. >> k
k =
1.0e+03 *
0.0124 8.6000 0.0308
0.0099 9.8400 0.0355

tri = delaunay(k(:,1),k(:,2));
trisurf(tri,k(:,1),k(:,2),k(:,3))

The surface in your image is provided on a regular grid, while your data are not. You need to interpolate your data on a structured grid (created with meshgrid) using scatteredInterpolant.
k = 1.0e+03 *[ 0.0124 8.6000 0.0308

0.0100 8.4900 0.0372];
f = scatteredInterpolant(k(:,1),k(:,2),k(:,3),'natural','linear');
[x,y] = meshgrid(linspace(min(k(:,1)),max(k(:,1)),50),linspace(min(k(:,2)),max(k(:,2)),50));
z = f(x,y);
figure
surf(x,y,z)
