| x | the numeric result, or [] when the text cannot be evaluated to a number. |
| ok | a logical: true when the conversion succeeded. |
x = str2num(s) converts the character array s to a numeric array by evaluating it.
Because str2num evaluates its input, prefer str2double for simple scalar conversions.
