Mean value of each cell of 2D grid

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?

How did you make a 2dgrid with cells?

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);
