I have a 4D matrix G size of [k*j*i*l] so its G(k,j,i,l) ,
the sizes are:
k=1x365,
j=1x31,
i=1x24,
l=1x91.
For estimation purposes I need a 3D matrix G(k,j-i,l), which I can later also plot.
I did not try anything, since I have no clue how to do it.
Thanks

dear Guillaume
sorry for the confusion, the last dimension is not 1 (one) but l (L), j-i is a new dimension that is equal to j-i, but because j-i is for each values of j and i it becomes a matrix j-i(j,i) instead of an array. Here my imagination stops working, I cannot figure out how it should be. Or maybe I am wrong and the solution looks otherwise.
thanks

dear madhan ravi
I did not remove or edit it since the first posted, it must have been a system fault maybe.

I am not certain what you want.
Try this:
G = rand(365,31,24,91); % Create ‘G’
Gnew = reshape(G, 365, [], 91); % Desired Result (?)
Experiment to get the result you want.
