Hi there,

I have a question regarding Mata. Suppose I have an imaginary matrix
with two columns as follows,
x                      y
2.9479707       .15
2.926226         .16
2.8994321       .17
2.8691981       .18
2.8368784       .19
2.8035694        .2
2.7701303       .21
2.7372142       .22
2.705299         .23
2.6747184        .24

I want Mata to return the maximum values of column 1 (x) AND its
corresonding values in column 2 (y), in this example, 2.9479707 and
0.15. I understand I can use -rowmax- to find the maximum, but I am
not quite sure how to find the corresponding value.

Thanks.

Le
