    Matrix operators


{title:Description}

{pstd}
Matrix operators are outlined here.  See {helpb matrix} for background
information and links to more matrix help.

{pstd}
Let {it:B} and {it:C} represent matrix names or matrix expressions.  Let
{it:z} represent numbers or scalar expressions.

{pstd}
The matrix monadic operators are

	{cmd:-}{it:B}      negate
	{it:B}{cmd:'}      transpose

{pstd}
The matrix dyadic operators are

{p 8 18 2}{it:B} {cmd:\} {it:C} {space 1} add rows of {it:C} below rows of
	{it:B}{p_end}
{p 8 18 2}{it:B} {cmd:,} {it:C} {space 1} add columns of {it:C} to the right of
	{it:B}{p_end}
{p 8 18 2}{it:B} {cmd:+} {it:C} {space 1} add{p_end}
{p 8 18 2}{it:B} {cmd:-} {it:C} {space 1} subtract{p_end}
{p 8 18 2}{it:B} {cmd:*} {it:C} {space 1} multiply (including mult. by
	scalar){p_end}
{p 8 18 2}{it:B} {cmd:/} {it:z} {space 1} division by scalar{p_end}
{p 8 18 2}{it:B} {cmd:#} {it:C} {space 1} Kronecker product

{pstd}
Parentheses may be used to enforce a particular order of evaluation.
