Combine several matrix with NaNs
I need to combine several matrixes of 500×500 elements that contains NaN. The matrixes must be combined in the way they keep their size but replace NaN by the elements of the other matrix.
I can easily do it for two matrixes:
% Cx is a strucutre that I use to store these matrixes. Cx has several matrixes e.g Cx(1).Z Cx(2).Z …
or=Cx(1).Z; %I want to add the elements to the first matrix (or)
nr=Cx(2).Z; % this is the second matrix
xn=isnan(or); %I select the NaN’s
or(xn)=nr(xn); %I can get now combined elements between Cx(1).Z and Cx(2).Z, it works good until here
%I need to do the same now for all the other matrixes in my structure (Cx),so the combination will be cummulative, I mean use the resulting matrix from merging Cx(1).Z and Cx(2).Z to merge with Cx(3).Z, and then use this output to merge with Cx(4).Z …. and so on
I tough that a loop would be usefull
or=Cx(1).Z;
xn=isnan(or);
for i=1:numel(Cx)
nr=Cx(i).Z;
or(xn)=nr(xn);
end
but the output or is constantly overwrited and I can get a combination of the matrixes
any suggestion?
