{title:Description}

{pstd}
{cmd:matrix dir} lists the names of currently existing matrices.
{cmd:matrix list} lists the contents of a matrix.  {cmd:matrix rename} changes
the name of a matrix.  {cmd:matrix} {cmd:drop} eliminates a matrix.


{title:Options}

{phang}
{cmd:noblank} suppresses printing a blank line before printing the
matrix.  This is useful in programs.

{phang}
{cmd:nohalf} specifies that, even if the matrix is symmetric, the full
matrix is to be printed.  The default is to print only the lower triangle in
such cases.

{phang}
{cmd:noheader} suppresses the display of the matrix name and dimension
before the matrix itself.  This is useful in programs.

{phang}
{cmd:nonames} suppresses the display of the bordering names around the
matrix.

{phang}
{cmd:format(%}{it:fmt}{cmd:)} specifies the format to be used to
display the individual elements of the matrix.  The default is
{cmd:format(%10.0g)}.

{phang}
{cmd:title(}{it:string}{cmd:)} adds the specified title {it:string} to the
header displayed before the matrix itself.  If {cmd:noheader} is specified,
{cmd:title()} does nothing because displaying the header is suppressed.

{phang}
{cmd:nodotz} lists {cmd:.z} missing values as blanks.


{title:Examples}

    {cmd:. matrix list mymat}
    {cmd:. matrix rename mymat alpha}
    {cmd:. mat drop alpha}
    {cmd:. mat dir}
