{p 4 4 2}
{bf:[M-5] mod() -- Modulus}


{title:Syntax}

{p 8 12 2}
{it:real matrix} {cmd:mod(}{it:real matrix x}{cmd:,} {it:real matrix y}{cmd:)}


{title:Description}

{p 4 4 2}
    {cmd:mod(}{it:x}{cmd:,} {it:y}{cmd:)} returns the elementwise modulus
    of {it:x} with respect to {it:y}.  
    {cmd:mod()} is defined

	{cmd:mod(}{it:x}{cmd:,} {it:y}{cmd:)} = {it:x} - {it:y}*trunc({it:x}/{it:y})


{title:Conformability}

    {cmd:mod(}{it:x}{cmd:,} {it:y}{cmd:)}:
	{it:x}:  {it:r1 x c1}
	{it:y}:  {it:r2 x c2}, {it:x} and {it:y} r-conformable
   {it:result}:  max({it:r1},{it:r2}) {it:x} max({it:c1},{it:c2}) (elementwise calculation)


{title:Diagnostics}

{p 4 4 2}
    {cmd:mod(}{it:x}{cmd:,} {it:y}{cmd:)} returns missing when either argument
    is missing or when {it:y}==0.
