How to merge similar matrixes and list them on columns.

 Hi Matlab users,

OK, so I have a 238x132 matrix representing current movements in one day(let's call it U), and two 238x132 matrixes representing one Latitude and one Longitude (they are like this because they are gridded). What I need to do is to put all three of them on columns like this: Latitude Longitude U where Latitude and Longitude have the same positions inside their matrixes as U.

I can do it like this: U11=[Latitude(1,1) Longitude(1,1) U1(1,1)]; but it takes a lot of time. Is there a easier way?

I am really ashamed for not knowing this.

Umn = [Latitude(:) Longitude(:) U(:)];

other variant

M = cat(3,Latitude,Longitude,U);
C = cellfun(@(x)x(:)',num2cell(M,3),'un',0);
out = cell2mat(C);

more variant

M = cat(3,Latitude,Longitude,U);
out = reshape(permute(M,[3 2 1]),[],size(U,1))';

or

M = [Latitude(:),Longitude(:),U(:)];
out = reshape(permute(reshape(M',3,size(U,1),[]),[2 1 3]),size(U,1),[]);

Thank you, it works.
