Hi I am trying to solve a problem that has x,y data and f(x,y). It's a 2D temp map with f(x,y) being temperature values.
I have too many x (3000 values) and y (3000) values and f(x,y) (3000) values.
When I plot surface 2D it generates very odd map with too much of data. To avoid that I am looking to reduce the number of grid points by taking some avg. This way I can reduce the number of grid points.
Can any one has suggestions how to do matlab code for this?

Look at Jan's answer here. He provides MATLAB code and a refernce to the File Exchange. For your convienance:
X = rand(20, 30);
R = reshape(X, 2, 10, 2, 15);
S = sum(sum(R, 1), 3) * 0.25;
Y = reshape(S, 10, 15);
