Methods summary
`public Structure`	# `__construct( $A )` LU Decomposition constructor. LU Decomposition constructor. Parameters `$A` matrix Returns Structure to access L, U and piv.
`public array`	# `getL( )` Get lower triangular factor. Get lower triangular factor. Returns array Lower triangular factor
`public array`	# `getU( )` Get upper triangular factor. Get upper triangular factor. Returns array Upper triangular factor
`public array`	# `getPivot( )` Return pivot permutation vector. Return pivot permutation vector. Returns array Pivot vector
`public`	# `getDoublePivot( )` Alias for getPivot Alias for getPivot See `PHPExcel_Shared_JAMA_LUDecomposition::getPivot()`
`public true`	# `isNonsingular( )` Is the matrix nonsingular? Is the matrix nonsingular? Returns true if U, and hence A, is nonsingular.
`public array`	# `det( )` Count determinants Count determinants Returns array d matrix deterninat
`public X`	# `solve( $B )` Solve AX = B Solve AX = B Parameters `$B` Matrix with as many rows as A and any number of columns. Returns X so that LUX = B(piv,:) Phpexcel_calculation_exception IllegalArgumentException Matrix row dimensions must agree. RuntimeException Matrix is singular.

Constants summary
`string`	`MatrixSingularException`	# `"Can only perform operation on singular matrix."`
`string`	`MatrixSquareException`	# `"Mismatched Row dimension"`
