The result will probably be a cell array containing the vector that you want.

OK, simple but NOT obvious. It took me a while to see how this trick works, and why '12345' - '0' does not equal '12345' + '0'. A hint, 'b' - 'a' = 'c' - 'b' = 1.

I suppose I should point out that the "trick" works because the character encoding scheme in use has the characters '0', '1', ..., '9' all next to each other and different by 1. e.g., this is true of ASCII and EBCDIC encoding. Also, subtracting character values in MATLAB automatically promotes the result to a double type. James Tursa

"Ingenious use of relatively cryptic MATLAB functionality", maybe?

No offense taken ... I sometimes "post-in-haste" and additional enlightening comments by others never hurt :) James Tursa
