regex - Attach a string to every group of substrings separated by a set of symbols -

-

imagine have string

newton = 'kg*m/s^2'

and need be:

newtonmupad = 'unit::kg*unit::m/unit::s^2'

is there simple way detect every physical unit , attach unit:: it? can assumed every unit seperated either /, * or exponent ^2 or ^3.

for used several regular expressions, like

x = regexp(newton ,'*','split') y = regexp(newton ,'/','split') z = regexp(newton ,'^','split')

and i'm able create string need loop. wonder if there simpler , faster solution using matlab?

you can use regexprep:

>> newton = 'kg*m/s^2' >> regexprep(newton,'(([a-za-z]+)(*|/|\^|$))', 'unit::$1')  ans =   unit::kg*unit::m/unit::s^2

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...
