Is it possible to use the smooth function with a multidimensional matrix having NaN values?

The NaN values would be the points where the smooth function generates the new values.

Hope this is clear. Thank you!

Thank you but I have a matrix with 5 dimensions...

I tried using https://www.mathworks.com/matlabcentral/fileexchange/25634-smoothn?s_tid=srchtitle but I keep getting the errors:

Matrix dimensions must agree.

Error in smoothn>dctn (line 704)

y = y.*w{dim}(:,ones(1,n));

Error in smoothn>@(x)dctn(x) (line 632)

z = cellfun(@(x) dctn(x),z,'UniformOutput',0);

Error in smoothn>InitialGuess (line 632)

z = cellfun(@(x) dctn(x),z,'UniformOutput',0);

Error in smoothn (line 421)

z = InitialGuess(y,IsFinite);
