Reducing the resolution of a matrix

Hello,

I have a DEM that has a 2m resolution, and I would like to reduce this resolution to 250m so I can work with a temperature matrix on the same area.

Is there any way on Matlab to reduce the resolution of such a matrix ? I want both my matrices to be the same size over the same area so when I do some calculations on certain points, I don't have to find systematically the nearest neighbour.

Have a nice day !

Read about interp2. You have to do interpolation.
