Hi,
I am trying to unfold a matrix in the form I x J x K to I x JK corresponding to I batches, J variables and K time periods (within the batch).
I currently have got this matrix:

And I need it in the form:
![batch wise unfold matrix.PNG](https://www.mathworks.com/matlabcentral/answers/uploaded_files/232220/batch%20wise%20unfold%20matrix.png)
How would I go about doing this as I think reshape is inadequate?
Thanks

"I am trying to unfold a matrix in the form I x J x K to I x JK"
May be: Are you looking for this one?
[R C D]=size(M);
X=reshape(M,R,C*D)
I ignored this part "corresponding to I batches, J variables and K time periods (within the batch). "
