I am trying to replace NaN's in a vector field with the nearest neighbor. I believe I can use knnsearch to find the indices of the nearest neighbor to each NaN, but am running into problems. Here is what I have so far: u = median_u; %u & v are 47x47x309. v = median_v; k = [1 0 -1]; s = [47 47]; u_bad = isnan (u);
