Using interp2 to interpolate points on a path

load('ProjectTerrain.mat');
for k=1:500
xxx=[-4.8:k:4.8];
yyy=[4:k:-4.8];
a(k)=interp2(x,y,T,xxx,yyy);
end
I have a dataset of 3D terrain data that gives the elevation at certain points (x,y,T), and am trying to interpolate points on a path 500 steps long but am not sure how to start. The coordinates for the start and end points are in xxx and yyy.

The loop is unnecessary. Try something like this:
load('ProjectTerrain.mat')
xxx = linspace(-4.8,4.8,500);
yyy = linspace(4,-4.8,500);
TTT = interp2(x,y,T,xxx,yyy);
