Changing Matrix dimensions from 4D to 2D: Matrix Manipulation, while preserving order of the data.

1 回表示 (過去 30 日間)
Hello everyone, I would like some feedback, please, on how to change a matrix from 4D to 2D. The original Matrix is M: (5*5*14680*30) and I need to import it to excel so I can extract some data since I couldn't find a way to do it effectively in Matlab. The big dataset M is basically made up of 30 blocks of 14680 of 5*5 matrices. By changing its dimensions from 4D to 2D, I expect my new matrix to have the following dimensions: 73400*150 (that's 5*14680 row and 5*30 columns). The position of each 5*5 matrix along with every element in it has to stay intact. I attached a hand-drawn sketch to explain what I wrote.

newMatrix=reshape( permute(M,[1,3,2,4]) , [], 150);

Try inserting a comma
newMatrix=reshape( permute(M,[1,3,2,4]), [], 150);

newMatrix=cell2mat( reshape( num2cell(M,[1,2]) ,[],30) );
