Actually the data I have has latitude(x) and longitude(y) of a road and also I have height of the road (z). Now I want to construct a plot which has shows height too and that height should be color coded. How can I do that ?

Are you trying to plot a top view of the roads and indicate the height of each road?

Yes that is what I want. I copied a data in below comment which include longitude, latitude and height

Read about surf. It also depends on what data you have and how want to show up the plot. More help on sharing the data and showing your expectations.

Yes I think its helping out. Thanks

Your data is huge, you need to restrict the data to a certain limit, plot and then see.

I guess you want to show something like this. Because the data is dense, it is not recommended to show the height of every point. But you can definitely adjust how and which particular point/region that you want to show the heights.
plot(A, B)
for t = 1:4379:numel(A)
text(A(t) + 0.0001, B(t) + 0.0001, ['(',num2str(C(t)),')'])
end

Wait. I think you need to consider the Earth radius (6371 km) in order to project the location of the points on the curved surface in Cartesian coordinates.
And then at each point, you want to show the elevation in the C.mat data using the color gradient. I think the z coordinate in not needed.
x = (6371).*cos(B).*cos(A);
y = (6371).*cos(B).*sin(A);
z = (6371).*sin(B);

Is the road curved? We need you to confirm.
x = (6371).*cos(B).*cos(A);
y = (6371).*cos(B).*sin(A);
scatter(x, y)
