FLHessen: Hessenberg Decomposition of a Matrix.

In Fuzzy-Logix/AdapteR: Converts R syntax to SQL to provide fast analytics using in-database C++ library DB Lytix.

Description

FLHessen computes the Hessenberg decomposition for FLMatrix objects.

Usage

FLHessen(object, ...)

Arguments

object	is of class FLMatrix
...	any additional arguments

Value

FLHessen returns a list of two components:

P	FLMatrix representing P matrix obtained from Hessenberg decomposition
H	FLMatrix representing H matrix obtained from Hessenberg decomposition

Constraints

Input can only be square matrix with maximum dimension limitations of (700 x 700). If the matrix is non-symmetric FLJordan() will run slower.

Examples

flmatrix <- FLMatrix(getTestTableName("tblMatrixMulti"), 5,"MATRIX_ID","ROW_ID","COL_ID","CELL_VAL",dims= c(5,5))
resultList <- FLHessen(flmatrix)
resultList$P
resultList$H
