    {cmd:mat_put_rr} {it:matname}


{title:Description}

{pstd}
{cmd:mat_put_rr} is a programmer's command that posts {it:matname} as the
internal {cmd:Rr} matrix.  {it:matname} must have one more column than the
{cmd:e(b)} and {cmd:e(V)} matrices.  The extra column contains the {cmd:r}
vector and the earlier columns contain the {cmd:R} matrix for the Wald test

{center:{cmd:Rb} = {cmd:r}}

{pstd}
See {hi:[R] test}.

{pstd}
The {cmd:matrix} ... {cmd:get(Rr)} command provides a way to obtain the
current {cmd:Rr} system matrix; see {helpb get()}.


{title:Example}

{phang2}{cmd:. regress y x1 x2 x3 x4}{p_end}
{phang2}{cmd:. mat z = (1,0,0,-1,0,2.8 \ 1,0,-1,0,0,0)}{p_end}
{phang2}{cmd:. mat_put_rr z}{p_end}
{phang2}{cmd:. test}

{pstd}
gives the same result as

{phang2}{cmd:. regress y x1 x2 x3 x4}{p_end}
{phang2}{cmd:. test x1-x2=2.8, notest}{p_end}
{phang2}{cmd:. test x1-x3=0, accum}
