split numbers into columns

I have a column vector, A which is 1x1500, and each element in each row contains several variables in each element. I would like to split these into separate columns. In the columnvector each element has 15 numbers, like A(1,1)= 123456789123456. And what I would like to have is B1 = 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6.

Basically, I'm looking for a line of code which can add space between each number in the elements of my column vector. Anyone knows?

"I have a column vector, A which is 1x1500"

If it has one row and 1500 columns that makes it a row vector.

"A(1,1)= 123456789123456"

You do not tell us anywhere what class the array has: is this a numeric array, or an cell array or character vectors, or something else? Your description is ambiguous, yet the answer you need will depend on the data type that you are working with.

I made a typo on the dimensions, it is 1500x1. So, I'm looking for a command that in general would create space between numbers in a vector, or pick out parts of elements in a vector. I would know how to pick out elements of course, but not parts of elements..

Thanks KL! Got it now :)

If the input is numeric, try this:

num = 123;
num2str(num)-'0'
