Hello!
I would like to reshape/transform matrices with 3D data (see attached photo). Is there an existing method for this?
Thank you

Initial situation:
X=[1;2;3]; Y=[1,2,3]; Z=[1,2,3;4,5,6;7,8,9];
Target:
X=[1;1;1;2;2;2;3;3;3]; Y=[1;2;3;1;2;3;1;2;3]; Z=[1;2;3;4;5;6;7;8;9];

[y,x] = ndgrid(Y,X);
x = x(:);
y = y(:);
z = reshape(Z',[],1);

@Manuela Gräfe: ndgrid does not require its inputs to have the same number of elements:
>> [Xm,Ym] = ndgrid(1:2,1:9); % no error!

So you have an error but you did not show us the complete error message and you did not show us the code... If you actually want help then you should show us what you tried and the complete error message. Thia means all of the red text.
