Converting a String to an Array

Hello!

I was wondering how to go about converting a string into an array like

x = [1 2 3 1 2 3 1 2 3]

1 2 3 1 2 3 1 2 3

into

x = [1 2 3; 1 2 3; 1 2 3]

1 2 3

1 2 3

1 2 3

I would like to apply this to a case where I have a string with 10,000 entries and would like to turn that string into a 100 x 100 array.

Thanks for looking at my problem.

If what you are really asking is "how do I turn a row vector into a rectangular matrix" then you can use RESHAPE.

x = [3 5 2 6 8 22 3 0 9 8 2 5]
y = reshape(x,4,[])'
