convert 3d cell array in 2d cell array

Question

I transformed a structure S (with 13 fields and 96 rows, some fields are made of numbers, others of strings) into a cell array:

myCell= struct2cell(S);

So, I obtained a 3d cell array myCell 13x1x96, and I would like to transform it in a 2d cell array 96x13. Any suggestion is welcome!

something like (squeeze(myCell)).' perhaps? The squeeze removes the singleton dimension. — Ben

@Benoit_11, thanks for your answer. I tried, and now myCell is 13x96, so at least 2d cell array, which is very good :). How can I now swap the rows with the columns and viceversa, in order to have myCell as 96x13? — dede

A more general solution than what was suggested would employ the permute function:

B = permute(A,order) rearranges the dimensions of A so that they are in the order specified by the vector order.

...

permute and ipermute are a generalization of transpose (.') for multidimensional arrays.

In your case, running the command new_Cell = permute(myCell,[3,1,2]) would make the 13x1x96 96x13. As you can see, permute removes trailing singleton dimensions (resembling squeeze).

(Tested on MATLAB 2015b)
