I have some data captured from a sensor by way of microsoft excel, the data is in the form of a 2D array, 900 rows and 15360 columns.

each row actually represents a 2d array in itself, and i need to turn the entire thing from a 2d array into a 3d one.

i.e the array is currently:

2  3  4   5  6
8  9  10  11 12
14 15 16  17 18

and needs to be in the format of

I've used the permute funtion to get

2 3 4 5 6 
8 9 10 11 12
14 15 16 17 18

but when i try and use the reshape function on this array i get the following error - Index exceeds matrix dimensions.

Any help will be greatly appreciated.

Is this what you mean?

permute(reshape(A',[3 2 3]),[2 1 3])
