I have a 3d (z,x,y) matrix and trying to fill NaN's in the each grid point in xy directions with the nearest value correspond to the previous layer (level).
Any help and information will be helpful. Thank you

B = reshape(T,[],1);
lo = ~isnan(T);
ii = find(lo);
C = interp1(ii,B(lo),(1:numel(B))','previous');
T_out = reshape(C,size(T));

fillmissing(your3darray, 'previous', 3) %fill nans with previous element along 3rd dimension
Possibly, with an optional 'EndValues', 'next' if you want to fill NaNs on the 1st layer with the next non-Nan value.

fillmissing requires R2016b or later. There is a field up there in the right corner of the page where you can enter which release you're actually using so we don't have to guess which functions may or may not be available to you.
