Hi all,

I am trying to get row name of a max value in a matrix. Previously i did install matsort and tabstatmat and mix both commands with st_matrixrowstripe but fail in the last step, my example code
Code:
sysuse auto, clear
*previously install tabstatmat
tabstat mpg, by(foreig) stat(mean sd) save
tabstatmat x, nototal
*previously install matsort
matsort x 1 "down"
mat li x
                   mean         sd
Domestic:mpg  24.772727  6.6111869
 Foreign:mpg  19.826923  4.7432972

local max = x[1,1]

mata : st_matrixrowstripe("x")
              1          2
    +-----------------------+
  1 |  Domestic        mpg  |
  2 |   Foreign        mpg  |
    +-----------------------+

local rownames = x[1,1]
di "`rownames'"
Please any advice I will grateful.
Best regards
