st: Results displayed in parentheses after -matrix-

[Herve STOLOWY <stolowy@hec.fr>]

Dear Statalisters:

I run a ttest and get some results in a matrix.

ttest offer, by(info), if risk==0 &  round>7 & round<26 
matrix m_lowrisk2=r(sd_1), r(sd_2)

Is there a way to get r(sd_1) and  r(sd_2) displayed in parentheses in the matrix? 

I have seen the option format after matrix but I don't know how to use it.

Best regards

Herve Stolowy
