times: Element-Wise Multiplication of in-database objects.

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

Description

* does the Element-wise Multiplication of in-database objects.

Usage

"*"(pObj1, pObj2)

Arguments

pObj1	can be an in-database object like FLMatrix,FLSparseMatrix,FLVector or a normal R object like matrix,sparseMatrix,vector
pObj2	can be an in-database object like FLMatrix,FLSparseMatrix,FLVector or a normal R object like matrix,sparseMatrix,vector

Details

The Element-wise Multiplication of in-database objects mimics the normal Element-wise Multiplication of R data types. All combinations of operands are possible just like in R and the result is an in-database object.

Value

* returns an in-database object if there is atleast one in-database object as input.Otherwise, the default behavior of R is preserved

Examples

flmatrix <- FLMatrix("tblMatrixMulti", 1,"MATRIX_ID","ROW_ID","COL_ID","CELL_VAL")
Rvector <- 1:5
ResultFLmatrix <- flmatrix * Rvector
