4D matrix manipulation

Question

0 个投票

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.
