List of increasing integers

I have a list of dimensions given by the row vector as follows

I would like to associate with this vector, a list of increasing integers such that each size in 'dim' corresponds with an exact number of integers like this:

int = [ 1 2 , 3 4, 5 6 7 8, 9 10, 11 12, 13 14, 15 16, 17 18, 19 20, 21 22, 23 24, 25 26]

I grouped the integers just to indicate that a dim=4 corresponds to 5 6 7 8. and the rest just has two integers.

Thanks.

dim = [2 2 4 2 2 2 2 2 2 2 2 2]

dim = 1×12

2 2 4 2 2 2 2 2 2 2 2 2

int = 1:sum(dim)

int = 1×26

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

out = mat2cell(int, 1, dim)

ans = 1×12 cell array
    {[1 2]}    {[3 4]}    {[5 6 7 8]}    {[9 10]}    {[11 12]}    {[13 14]}    {[15 16]}    {[17 18]}    {[19 20]}    {[21 22]}    {[23 24]}    {[25 26]}

This is what I needed. To have it all in a cell. Thank you!

You're welcome!

Are you sure that is what you want? It doesn't seem very useful.

dim = [2 2 4 2 2 2 2 2 2 2 2 2]

dim = 1×12

2 2 4 2 2 2 2 2 2 2 2 2

int = 1:sum(dim)

int = 1×26

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

int(end)

ans = 26

Thank you very much. It's very useful for what i'm working on.
