Matrix arrayLeftDivide( Matrix $B)
Element-by-element Left division A / B
Matrix arrayLeftDivideEquals( mixed $B)
Element-by-element Left division Aij = Aij / Bij
PHPExcel_Shared_JAMA_Matrix __construct( )
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.
