Methods summary
`public`	# `__construct( )` Polymorphic constructor Polymorphic constructor As PHP has no support for polymorphic constructors, we hack our own sort of polymorphism using func_num_args, func_get_arg, and gettype. In essence, we're just implementing a simple RTTI filter and calling the appropriate constructor.
`public array`	# `getArray( )` getArray getArray Returns array Matrix array
`public integer`	# `getRowDimension( )` getRowDimension getRowDimension Returns integer Row dimension
`public integer`	# `getColumnDimension( )` getColumnDimension getColumnDimension Returns integer Column dimension
`public mixed`	# `get( integer $i = null, integer $j = null )` get get Get the i,j-th element of the matrix. Parameters `$i` Row position `$j` Column position Returns mixed Element (int/float/double)
`public Matrix`	# `getMatrix( integer $i0,…, integer $iF,…, integer $j0,…, integer $jF,… )` getMatrix getMatrix Get a submatrix Parameters `$i0`,… Initial row index `$iF`,… Final row index `$j0`,… Initial column index `$jF`,… Final column index Returns Matrix Submatrix
`public boolean`	# `checkMatrixDimensions( Matrix $B = null )` checkMatrixDimensions checkMatrixDimensions Is matrix B the same size? Parameters `$B` Matrix B Returns boolean
`public mixed`	# `set( integer $i = null, integer $j = null, mixed $c = null )` set set Set the i,j-th element of the matrix. Parameters `$i` Row position `$j` Column position `$c` Int/float/double value Returns mixed Element (int/float/double)
`public Matrix`	# `identity( integer $m = null, integer $n = null )` identity identity Generate an identity matrix. Parameters `$m` Row dimension `$n` Column dimension Returns Matrix Identity matrix
`public Matrix`	# `diagonal( integer $m = null, integer $n = null, mixed $c = 1 )` diagonal diagonal Generate a diagonal matrix Parameters `$m` Row dimension `$n` Column dimension `$c` Diagonal value Returns Matrix Diagonal matrix
`public Matrix`	# `getMatrixByRow( integer $i0 = null, integer $iF = null )` getMatrixByRow getMatrixByRow Get a submatrix by row index/range Parameters `$i0` Initial row index `$iF` Final row index Returns Matrix Submatrix
`public Matrix`	# `getMatrixByCol( integer $j0 = null, integer $jF = null )` getMatrixByCol getMatrixByCol Get a submatrix by column index/range Parameters `$j0` $i0 Initial column index `$jF` $iF Final column index Returns Matrix Submatrix
