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

Description

tr computes the trace of FLMatrix objects.

Usage

tr(object, ...)

Arguments

object	an object of class FLMatrix
...	any additional arguments

Details

tr computes the trace of input FLMatrix object, stores the result in-database and returns R vector object

Value

tr returns R Vector object of size 1 which replicates the equivalent R output.

Constraints

Input matrix can only be square matrix with maximum dimension limitations of (1000 x 1000).

Examples

flmatrix <- FLMatrix(getTestTableName("tblMatrixMulti"), 5,"MATRIX_ID","ROW_ID",
                      "COL_ID","CELL_VAL",dims= c(5,5))
resultFLVector <- tr(flmatrix)
