How to divide a string into multiple rows

If I have a string e.g.

A= 1 2 3 4 5 6 7 8 9

How can I change that into: [1 2 3;4 5 6;7 8 9]

1 2 3

4 5 6

7 8 9

If I use the reshape command e.g. reshape(A,3,[]) it will turn it into

1 4 7

2 5 8

3 6 9

But I need it to be like: [1 2 3;4 5 6;7 8 9]

Transpose after doing the reshape call:

A = [1     2     3     4     5     6     7     8     9];
Ar = reshape(A,3,[]).'

Ar = 3×3

1 2 3 4 5 6 7 8 9

.

Thank you so much my example isn't very good because it still doesn't really solve my problem. The rows and colums swapped but I don't want it to transpose e.g.

A=[1,2,3,4,5,6,7,8,9,10]

if I used

reshape(A,2,[]).'

that will give me

1 2

3 4

5 6

7 8

9 10

but I want it to be

1 2 3 4 5

6 7 8 9 10

How can I achieve that

My pleasure!

The reshape function can’t do everything, however it can produce that result. It’s necessary to experiment with it to get the result you want.

Here —

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

Ar = 2×5

1 2 3 4 5 6 7 8 9 10

As desired.

It’s certainly possible to want a result it can’t produce, even with transposition or with permute (essentially multi-dimensional dimension-shuffling), so it definitely has its limitations.
