{p 8 15 2}{cmdab:mat:rix} {cmdab:cole:q} {space 2} {it:A} {cmd:=} {it:names}

{pstd}
where {it:name} can be

{phang2}(1) a simple name{p_end}
{phang2}(2) a colon followed by a simple name{p_end}
{phang2}(3) an equation name followed by a colon{p_end}
{phang2}(4) an equation name, a colon, and a simple name

{pstd}
and a simple name may be augmented with time-series operators.


{title:Description}

{pstd}
{cmd:matrix rownames} and {cmd:colnames} reset the row and column names of
an already existing matrix.  Row and column names may have three parts:

{phang2}{it:equation_name}{cmd::}{it:ts_operator}{cmd:.}{it:subname}

{pstd}
{cmd:matrix roweq} and {cmd:coleq} also reset the row and column names of
an already existing matrix but, if a simple name is specified (a name without
a colon), it is interpreted as an equation name.

{pstd}
The current row and column names of a matrix are obtained using extended macro
functions; see {help matmacfunc}.


{title:Examples}

{phang}{cmd:. matrix rownames A = price weight mpg}{p_end}
{phang}{cmd:. matrix rownames X = L3.price L2.price L1.price F.weight mpg}{p_end}
{phang}{cmd:. matrix coleq X = eq1 eq1 eq1 aux}{p_end}
{phang}{cmd:. matrix colnames Y = eq1:L.x eq1:x eq2:sigma}
