How do I smooth 2D vector field data?

I have a vector field in 2D. How can I smooth the data? I found smooth and smooth3 but it seems there is nothing for 2D. Could someone help me?

Split your vector field into components (how to do this depends on how it is stored to start with). Smooth each component separately and reassemble them if necessary.

To smooth a 2-D scalar array, you can use conv2 with a suitable kernel. The choice of kernel depends on how much you want to smooth and what your smoothing requirements are. Typically a Gaussian is a good choice - if you have the Image Processing Toolbox you can use fspecial to get one.
