I want to resize 2 arrays, A and B, to make them the same size.

BUT, array B has a lot of NaN value.

So, I only want to resize A to fit the numerical data in B, excluding the NaN values.

% The CODE to resize
C = imresize(A, size(B));
% How can I modify the size(B) part to exclude the NaN during the resize process?

You can fill the NaN's using fillmissing. And then use resize the way you want.

You can use interp2 to get them to the same size.

I could convert the NaN to 0 and maybe there is some code to ignore the 0 when doing the imresize?

Remove rows and columns with NaN.

A(all(isnan(A),2),:) = [] ;  % remove in NaN's rows 
A(all(:,isnan(A),1)) = [] ;  % remove rows in columns
