Reshaping array with specific order

Greetings,

I have a 2-D matrix that I would like to reshape into a 3-D array with specific ordering of the elements.

For example, if my 2-D matrix is

A = [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20];
B = reshape(A, 2, 5, [])

ans(:,:,1) =

     1     2     3     4     5
    11    12    13    14    15


ans(:,:,2) =

     6     7     8     9    10
    16    17    18    19    20

However, the order I am looking for through reshape is:

ans(:,:,1) =

     1     2     3     4     5
     6     7     8     9    10


ans(:,:,2) =

    11     12     13     14    15
    16     17     18     19    20

Any help with how I can do this?

Thank you.

Are you sure you have correct description of your problem?

A = [1 2 3 4 5; 6 7 8 9 10];
B = reshape(A, 2, 5, [])

B = 2×5

1 2 3 4 5 6 7 8 9 10

Can't be done with only reshape. You have only 10 elements in A and the requested output array requires 20.

OTOH, it's easy enough to produce the desired result by

>> A = [1 2 3 4 5; 6 7 8 9 10];
>> C=cat(3,A,A+10)
C(:,:,1) =
     1     2     3     4     5
     6     7     8     9    10
C(:,:,2) =
    11    12    13    14    15
    16    17    18    19    20
