Hi there!
I'm having trouble extracting a number from a data string that isn't always consistent.
I'm getting incoming strings that sometimes change their format, but will always have a number with a "G" after it. For example:
ans =
+1.4105 G 799 ON 1X OFF
ans =
isj34 ME102+03994 G
ans =
ME101-04230 G 17 OFF
It can be formatted a whole mess of ways, but the one thing that is consistent is the sign, number, and "G" after it. (there are blank spaces sometimes, the ME10# will sometimes be there, sometimes will not, and if it is, there's no guarantee that the # is 1 or 2)
I've tried using sscanf to simply extract the number, for example:
sscanf('silj 90 ME102-014830 G','ME102%f G',1)
or
sscanf('silj 90 ME102-014830 G','%*s ME102%f G',1)
or
sscanf('silj 90 ME102-014830 G','%*f ME102%f G',1)
and I'm looking for:
ans =
-14830
So far I've only gotten blank strings.
Open to any suggestions. Thanks!
