Forming a matrix from data

Hi,

I think I'm going mad, does anyone know why Matlab will not form a Matrix from the following. I've separated each of the 10 elements with a ; as it says in the help.

Kind regards,

Andy

To put elements on separate rows, you can either put a semicolon between the numbers, or enter them on separate lines. You have done both, so every number is being placed on a separate row. Place elements on the same line that you want in the same row, separated with a comma. Otherwise, use '...' to indicate the row continues on the next line.

Thank you Cris, it makes sense now. I think because I brought it in from a data set I got confused. Once again, thanks.
