__construct() __construct(mixed $Arg) : \Structure Construct the singular value decomposition Derived from LINPACK code. Parameters mixed $Arg Returns \Structure — to access U, S and V.
getSingularValues() getSingularValues() : \diagonal Return the one-dimensional array of singular values Returns \diagonal — of S.
rank() rank() : \Number Effective numerical matrix rank Returns \Number — of nonnegligible singular values.
